Abstract
A thin film transistor display that comprises a black matrix polymer layer, comprising a polymer having an optical density of at least about 0.8 per .mu.m and being self-absorbent of visible light and being selected from the group consisting of substituted and unsubstituted polyanilines, substituted and unsubstituted polyparaphenylenevinylenes, substituted and unsubstituted polythiophenes, substituted and unsubstituted polyazines, substituted and unsubstituted polyparaphenylenes, substituted and unsubstituted polyfuranes, substituted and unsubstituted polypyrroles, substituted and unsubstituted polyselenophene, substituted and unsubstituted poly-p-phenylene sulfides and substituted and unsubstituted polyacetylenes, and mixtures thereof, and copolymers thereof. The layer also comprises one or more pigments. The resistivity of the black matrix composite is 10E12 to 10E14 ohm cm.
