技术领域 FIELD

本发明涉及一种液晶显示装置,更具体地,涉及一种半透型液晶显示装置,其具有光透射型液晶显示装置和光反射型液晶显示装置的功能。 The present invention relates to a liquid crystal display device, and more particularly, relates to a transflective type liquid crystal display device having a light transmission type liquid crystal display device and a light reflection type liquid crystal display device.

背景技术 BACKGROUND

垂直排列(vertical-alignment)型液晶显示装置在未施加电场时,可以将光线完全遮住。 Homeotropic alignment (vertical-alignment) type liquid crystal display device when no electric field is applied, the light can be completely covered. 即,由于在标准黑模式下关断条件的亮度非常低,垂直排列型液晶显示装置与传统的扭转向列型液晶显示装置相比,可以表现出较高的对比率。 That is, since the normally black mode in OFF condition brightness is very low, a homeotropic alignment type liquid crystal display device with the conventional twisted nematic liquid crystal display device as compared, can exhibit a high contrast ratio.

通常,在液晶显示装置消耗的功率中,背光要消耗50%或更多。 Typically, the power consumption of the liquid crystal display device, the backlight consumes 50% or more. 因此,经常设计便携式通信装置,以包括光反射型液晶显示装置,光反射型液晶显示装置包括光反射器来代替背光源,只通过入射光来显示图像。 Thus, the portable communication apparatus are often designed to include a light reflection type liquid crystal display device, a light reflection type liquid crystal display device includes a light reflector instead of the backlight, to display an image only by the incident light.

但是,光反射型液晶显示装置的问题在于当装置周围比较黑暗时,不能看到所显示的图像。 However, the problem of light reflection type liquid crystal display device when the peripheral device is darker, the displayed image can not be seen.

作为这个问题的解决方案,提出了包括光反射区和光透射区的半透型液晶显示装置,作为具有光反射型液晶显示装置和光透射型液晶显示装置的优点的液晶显示装置。 As a solution to this problem is proposed comprising a light reflection area and the light transmissive area of transflective type liquid crystal display device, a liquid crystal having a light reflection type liquid crystal display apparatus is advantageous means and the light transmission type liquid crystal display of the display device. 例如,日本专利No.2955277已经提出了这样一种半透型液晶显示装置。 For example, Japanese Patent No.2955277 has proposed a transflective type liquid crystal display device.

在第一区120中,第一衬底101包括第一电绝缘透明衬底109、面向液晶层103的、在第一透明薄膜109上形成的钝化薄膜110、由ITO组成并在钝化薄膜110上形成的象素电极111、在象素电极111上形成并具有波形表面的介电层112、以波形结构覆盖介电层112并由铝组成的象素电极113、覆盖象素电极113的排列(alignment)薄膜114、在液晶层103的相对侧、在第一透明衬底109上形成的光补偿器115以及在光补偿器115上形成的偏振器116。 In the first region 120, the first substrate 101 includes a first electrically insulating transparent substrate 109, facing the liquid crystal layer 103, a passivation film 110 on the first transparent film 109 is formed by the ITO and the passivation film composed of 110 formed on the pixel electrode 111, is formed on the pixel electrode 111 and the dielectric layer has a waveform surface 112 to cover the pixel electrode waveform structure 112 by a dielectric layer 113 composed of aluminum, covering the pixel electrode 113 arrangement (alignment) film 114, on the opposite side of the liquid crystal layer 103, the transparent substrate 109 is formed on the first optical compensator and the polarizer 115 on the optical compensator 115 is formed of 116.

在半透型液晶显示装置100中,调整构成液晶层103的液晶分子,使得当在液晶显示装置100上未施加电场时,其主轴与第一和第二衬底101和102垂直。 In the transflective type liquid crystal display device 100, configured to adjust the liquid crystal molecules 103 of the liquid crystal layer, so that when an electric field is not applied to the liquid crystal display device 100, the shaft and the first and second substrates 101 and 102 vertically. 液晶分子具有负介电各向异性。 The liquid crystal molecules having a negative dielectric anisotropy.

图2是传统半透型液晶显示装置的第二示例的横截面视图。 Figure 2 is a cross-sectional view of the second example of the conventional transflective liquid crystal device is displayed.

图2所示的半透型液晶显示装置150与图1所示的半透型液晶显示装置100的区别在于第一区120中第一衬底101的结构。 Transflective liquid crystal shown in Figure 2 transflective type liquid crystal display device 150 shown in Fig. 1 show the difference between the structure of device 100 in that the first region 120 of the first substrate 101.

即,在半透型液晶显示装置150中,以由IT0组成的象素电极111覆盖由铝组成的象素电极113,并在象素电极111上形成排列薄膜114。 That is, the transflective type liquid crystal display device 150 to the pixel electrode 111 is covered by IT0 composed of the pixel electrode 113 composed of aluminum, and arranged in the film 114 is formed on the pixel electrode 111. 除了这个差别,半透型液晶显示装置150在结构上与半透型液晶显示装置100相同。 Except for this distinction, transflective-type liquid crystal display device 150 in structure and transflective type liquid crystal display apparatus 100 same.

图1所示的半透型液晶显示装置100如下显示图像。 Image display means 100 as shown in FIG. 1 transflective type liquid crystal display.

在第一区120中,外部光进入半透型液晶显示装置100,并在用作反射器的象素电极113被反射。 In the first region 120, the external light enters the transflective type liquid crystal display device 100, and the pixel electrode is used as the reflector 113 is reflected. 然后,反射光通过液晶层103和第二衬底102,到达观察者。 Then, the reflected light through the liquid crystal layer 103 and the second substrate 102 to reach the viewer.

在第二区121中,从安排在第一透明衬底109下面的背光源(未示出)发出的背光通过第一衬底101、液晶层103和第二衬底102,到达观察者。 In the second region 121, emitted from a backlight arranged on the first transparent substrate 109 below the backlight (not shown) through the first substrate 101, a liquid crystal layer 103 and the second substrate 102 to reach the viewer.

如上所述,鉴于在第一区120中,入射光在液晶层103中往复,在第二区121中,入射光只是一次性通过液晶层103,导致在液晶层103中的光程差。 As described above, in the light of the first region 120, the incident light in the liquid crystal layer 103 in reciprocation in the second region 121, the incident light through the liquid crystal layer 103 only one time, resulting in the liquid crystal layer 103 in the optical path difference. 为了避免这种光程差,将第一区120中的单元间隙Dr设计为第二区121中的单元间隙Df的大约一半,从而优化了由第一和第二区120和121之间的延迟差所引起的输出光的强度。 To avoid this optical path difference, the first zone 120 is designed to the cell gap Dr in the second area 121 about half the cell gap Df, thus optimizing the delay of the second zone 120 and 121 between the first and the caused by the difference between the intensity of the output light.

例如,将单元间隙Dr和Df分别设计为2μm和4μm。 For example, the cell gap Dr and Df were designed to 2μm and 4μm.

图2所示的半透型液晶显示装置150以与半透型液晶显示装置100相同的方式显示图像。 Figure 2 transflective type liquid crystal display device 150 shown in the same manner as apparatus 100 and the transflective-type liquid crystal display displays an image.

为了利用上述半透型液晶显示装置和垂直排列型液晶显示装置所提供的优点,日本专利申请公开No.2000-29010和No.2000-35570提出了具有半透型和垂直排列型液晶显示装置的功能的液晶显示装置。 In order to utilize the advantages of the above-described transflective type liquid crystal display device provided by the device and a vertical alignment type liquid crystal display, Japanese Patent Application Laid-Open No.2000-29010 and No.2000-35570 proposes transflective type and having a vertically aligned type liquid crystal display device The liquid crystal display device function.

为了避免液晶层103中的上述光程差,具有第一和第二区的半透型液晶显示装置不可避免地具有互不相同的单元间隙Dr和Df。 Transflective liquid crystal in order to avoid the above-mentioned liquid crystal layer 103 in the optical path difference, having first and second regions of the display apparatus inevitably have mutually different cell gap Dr and Df.

但是,互不相同的单元间隙Dr和Df引起了这样的问题:当将电场施加在液晶层上时,在第一和第二区之间的边界处及边界附近,液晶分子沿不一致的方向倾斜,导致清晰度的恶化和响应速度的降低。 However, mutually different cell gap Dr and Df caused such a problem: when the electric field is applied to the liquid crystal layer, at the boundary and near the boundary of the liquid crystal molecules in a direction along the inconsistency between the first and second inclined region , resulting in deterioration of the response speed and lower resolution.

本发明人实施了实验以了解依照第一到第三实施例的液晶显示装置中,在施加电场时液晶的行为。 The present inventors have carried out experiments to find out in accordance with the first to third embodiment of the liquid crystal display device, when an electric field is applied to the liquid crystal behavior. 在图8到图10中示出了结果。 In FIG. 8 to FIG. 10 shows the results. 图8是沿图3A中的线AA得到的剖面图,图9是沿图4A中的线AA得到的剖面图,图10是沿图7中的线AA得到的剖面图。 8 is a sectional view taken along line AA in FIG. 3A obtained, FIG. 9 is a sectional view taken along the line AA in Figure 4A obtained, FIG. 10 is a sectional view taken along line AA in FIG. 7 obtained. 图8、图9和图10分别对应于第一、第二和第三实施例。 Figures 8, 9 and 10 correspond to the first, second and third embodiments.

当将电场施加在液晶层103中的液晶上时,第二实施例中的液晶的行为比第一和第三实施例中的都更为稳定,而第一实施例中的液晶的行为比第三实施例更为稳定。 When an electric field is applied to the liquid crystal in the liquid crystal layer 103, the second embodiment of the liquid crystal behavior than the first and third embodiments are more stable, whereas the first embodiment of the liquid crystal behavior than the first embodiment the third embodiment is more stable.

在第二实施例中,如图9所示,液晶借助于在象素电极111B中形成的第一开口区125B而倾斜,使得在比第一开口区125B更靠近倾斜表面122的区域中,液晶面向相对电极105的端指向倾斜表面122。 In a second embodiment, shown in Figure 9, the liquid crystal by means of a first opening area in the pixel electrode 111B 125B formed inclined so that the opening area than the first inclined surface 125B closer to a region 122, the liquid crystal electrode 105 facing the opposite end point to the inclined surface 122. 由于液晶以与倾斜表面122中的象素电极111倾斜的角度相同的角度倾斜,在液晶的排列方向上确保了自然的连续性。 Due to the inclined surface 122 of the pixel electrode 111 is inclined at the same angle of the liquid crystal is inclined, the liquid crystal alignment direction ensures natural continuity.

在第一实施例中,如图8所示,由于第一开口区125A,液晶垂直对准第一开口区125A的上方。 In a first embodiment, shown in Figure 8, since the first opening area 125A, the liquid crystal vertical alignment above the first opening portion 125A of. 第一区120中的液晶倾斜,使其面向相对电极105的端指向第二开口区135A,而第二区121中的液晶倾斜,使其面向相对电极105的端指向第二开口区135B。 The first region 120 of the liquid crystal is inclined so as to face the counter electrode terminal 105 of the second opening region, point 135A, while the second area 121 of the liquid crystal is inclined so as to face the counter electrode terminal 105 of the point to the second opening region 135B. 这样,液晶在关于倾斜表面122相对的两侧,沿相反的方向倾斜,确保了连续的排列形状。 Thus, the liquid crystal in the inclined surface 122 on opposite sides, inclined in opposite directions, to ensure a continuous arrangement of shapes.

在第三实施例中,如图10所示,在第一开口区125C和倾斜表面122之间的液晶倾斜,使得其面向相对电极105的端指向倾斜表面122,而相对于倾斜表面122越过第一开口区125C的液晶倾斜,使得其面向相对电极105的端远离倾斜表面122。 In a third embodiment, shown in Figure 10, the liquid crystal between the first opening portion 125C, and the inclined surface 122 is inclined so that its end opposite electrode 105 facing the inclined surface 122 directed, inclined with respect to the first surface 122 across the an opening area 125C of the liquid crystal is inclined such that its end facing away from the opposing electrode 105 inclined surface 122.

但是,由于在倾斜表面122上面的液晶以与倾斜表面所倾斜的角度相同的角度倾斜,液晶倾斜,使得只有在第一开口区125C和倾斜表面122之间的区域中,液晶面向相对电极105的端指向第一区120。 However, due to the inclined surface 122 inclined to the inclined upper surface of the liquid crystal is inclined at the same angle, the liquid crystal is inclined, so that at 125C, and only the inclined surface 122 of the region between the first opening region, facing the counter electrode 105 of the liquid crystal end point of the first zone 120. 结果,恶化了液晶分子排列方向的连续性。 As a result, the deterioration of the continuity of liquid crystal molecule arrangement direction.

第一开口区125B与凸台126A的共同之处在于这里都不形成象素电极111。 The first opening region 125B and the boss 126A is common where the pixel electrode 111 is not formed. 但是,与形成象素电极111的区域相比,第一开口区125B形成凹口,而凸台126A则凸出形成象素电极111的区域。 However, compared with the region forming the pixel electrode 111, the first opening region 125B formed recess, while the boss 126A of the area of the pixel electrode 111 is formed convex.

例如,凸台126A的高度在0.5到1μm的范围内。 For example, the height of the projection 126A is in the range of 0.5 to 1μm.

类似于依照第二实施例的半透型液晶显示装置20,如图9所示,通过形成凸台126A来代替第一开口区125B,同样可以一致定向液晶分子,可以减少清晰度的恶化和响应速度的下降。 In accordance with the second embodiment is similar to the transflective liquid crystal display device 20, shown in Figure 9, by forming a projection 126A in place of the first opening portion 125B, consistent orientation of the liquid crystal molecules can also be possible to reduce the deterioration of resolution and response slowdowns.
