PRODUCTION OF COLOR FILTER FOR LIQUID CRYSTAL DISPLAY BODY

摘要

PURPOSE:To improve a contrast ratio by tightly adhering a silver halide salt material to parts to be formed as picture elements or the entire surface thereof and exposing and developing said material through a mask to form a black matrix at the boundaries of the parts to be formed as the picture elements. CONSTITUTION:A color filter for a display body is produced by tightly adhering the silver halide salt material 4 to parts to be formed as the picture elements 2 or the entire surface thereof then forming the black matrix 3 to the boundaries of the parts to be formed as the picture elements 2 by exposing and developing said material through the mask 5. The silver halide salt material 4 tightly adhered to parts to be formed as the picture elements 2 or the entire surface thereof is sensitized by receiving the light transmitted through the mask 5. Said material is further subjected to an ordinary developing process or reversal developing process by which the parts irradiated with the light or the parts not irradiated with the light are reduced to pulverized metallic silver particles. The pulverized particles scatter light and function as the black matrix 3.
