GLASS PLATE FOR LIQUID CRYSTAL, COLOR FILTER FOR TFT LIQUID CRYSTAL, TFT LIQUID CRYSTAL DISPLAY FOR PROJECTION, AND COLOR TFT LIQUID CRYSTAL DISPLAY

摘要

Glass plate for liquid crystal, such that unecessary light in the areas except the pixel electrodes of the liquid crystal panel is completely shut off, the TFT light leakage current is eliminated, and reflection of light at the black matrix is suppressed. By using the glass plate, a color filter for TFT liquid crystal, TFT liquid crystal display for projection, color TFT liquid crystal display can be produced. An organic metal compound expressed by a general formula: M(OR₁)_m(OR₂)_nX_pY_q, or a mixture thereof is isolated by hydrolyzation. The sol is applied to a glass plate. In a porous transparent activated film formed by baking the coated glass plate, there is provided a black matrix produced by oxidation and reduction of metal and having a total reflectivity of 6% or less and an optical density of 3.5 or more.
