Abstract

A method of manufacturing a liquid crystal device is disclosed which comprises assembling together, in a layered structure, a pair of pre-shaped transparent plastic substrates (1, 1'), and a pair of transparent plastic films (5, 5') carrying a pair of conductive coatings (6, 6'). A plurality of spacers (9) are disposed between the plastic films and a partial adhesive seal (8) is provided around and/or between the films to provide a cavity therebetween. The cavity (7) is filled with a fluent liquid crystal mixture (7') or precursor mixture which is polymerisable to polymeric/liquid crystal composite material. The cavity is sealed to retain the liquid crystal mixture or composite material therein. At least one layer (4, 4') of a resilient transparent adhesive is disposed between two of the other layers of the device to enable the cell to be conformed to the required shape.
