Abstract
A thin film transistor liquid crystal device with color capabilities can be fabricated using polychromatic glass. Polychromatic glass is a full-color photosensitive glass in which colored regions can be established through exposure to ultraviolet radiation either concurrently with or followed by heat treatment. To assure that colored regions in the polychromatic glass are aligned with individual pel electrodes, each driven by a thin film transistor, the pel electrodes are used as a shutter to control the exposure of the polychromatic glass to the ultraviolet radiation.
