ABSTRACT:
There is provided a multicolor liquid crystal display comprising an integrated multilayer arrangement of the sequence: thick transparent plate, color filter, thin glass plate, liquid crystal, and thick glass plate, there being provided a transparent electrode pattern corresponding to that of the filter pattern, which electrode patterns are applied to the two surfaces which face the liquid crystal. The order of thickness of the thin glass plate is generally about 0.2 mm or less, and up to about 0.3 mm. The color filter may be in the form of a pattern of colored stripes or dots; there can also be used a multicolor filter comprising a pattern of stripes or dots of dichroic transmissive polarizing material, in conjunction with a polarizer applied to the rear plate of the device.
