Glass substrate for liquid crystals, color filter for TFT liquid crystals, TFT liquid-crystal display for projection, and color TFT liquid-crystal display

Abstract

Glass substrate for liquid crystals to secure high-contrast TFT liquid crystal displays, color filters for TFT liquid crystals, TFT liquid crystal displays for projection, and color TFT liquid crystal displays are obtained, in which unnecessary light of the region other than PIXEL electrodes of the liquid crystal panel can be completely shielded, TFT optical leak current can be completely suppressed, and light reflection at the black matrix portion can be nearly completely depressed. The glass substrate for liquid crystals of the present invention comprises a glass plate and a porous transparent active layer on said glass plate wherein said porous transparent active layer is prepared by hydrolyzing an organic metal compound represented by the general formula M(OR.sub.1).sub.m (OR.sub.2).sub.n X.sub.p Y.sub.q to form a sol, and then coating the sol on said glass plate, followed by baking to form said porous transparent active coating layer, and the active coating layer contains therein black matrix having 6% or less of a total reflection ratio by seeing-through from the glass surface and 3.5 or higher of an optical density.
