Abstract

PURPOSE:To reduce deterioration of color of a color filter by forming a photosensitive dyed film contg. a compd. having color developing function on the surface of a substrate, hardening selectively a specified region of the dyed film by exposing the film, removing the photosensitive dyed film on a region other than the exposed region, and subjecting the hardened photosensitive dyed film to fixing. CONSTITUTION:A photosensitive dyed film 1 contg. a color developable compd. is formed on the surface of an upper transparent glass substrate SUB 2, and a specified region of the photosensitive dyed film 1 is hardened by exposing selectively. The photosensitive dyed film 1 on the region other than the exposed region is removed, and each color filter R, G, and B is formed by subjecting the hardened photosensitive dyed film 1 to fixing. Since each color filter R, G, and B is formed by imparting color developing function to the photosensitive dyed film 1, a dyeing stage where a photoresist is used is eliminated. By this constitution, deterioration of color of a color filter is prevented, also the number of stage for forming a color filter is reduced.
