    Abstract: The invention is an improvement in a liquid crystal display device of the type having spaced front (10) and rear (12) glass panels, a transparent electrode layer (18), and an array of individually addressable pel electrodes (20) separated from the transparent electrode layer by a cavity filled with liquid crystal material (30). The improvement comprises a color filter layer in the form of a decal pattern (22). The decal pattern (22) is formed using interference film techniques which form an inorganic color filter. The decal is placed on one of the glass panels using known decal transfer methods. The inorganic nature of the color filter layer and the decal transfer methods allow for enhanced optical density of the color liquid crystal display.

    Abstract: The color filters required for a thin film transistor liquid crystal display device are provided by using polychromatic glass for either the front (38) or rear (54) glass panel of the device. Through a series of masking, ultraviolet exposure and heat treating steps, red, green, and blue color areas can be generated in the polychromatic glass. Each of the different colored areas is, of course, to be aligned with one of the individually-addressable pel electrodes (42A, 42B, 42C) in the device. In a first embodiment, the polychromatic glass forms the rear glass panel (54) of the device and serves as a substrate for the thin film transistors (44) used to individually address pel electrodes (42). In an alternate embodiment, the front glass panel (38) is treated to form the color filter regions.
