PURPOSE:To enable efficient and economical production by providing an active film layer which consists of a metal oxide on a transparent substrate and providing an ink layer of ink contg. a coloring material, then providing a resist layer thereon, thermally migrating the coloring agent into the active film layer to color the active film layer and removing the ink layer and the resist layer. CONSTITUTION:The active film layer 2 which consists of the metal oxide is formed on the transparent substrate 1 and the ink layer 3 is formed on the active film layer 2, following which the resist layer 4 is formed over the entire surface of the ink layer 3. The coloring material in the ink layer 3 is thermally migrated into the fine pores of the active film layer 2 to color said layer. The active film layer 2 is then sealed at need and the unnecessary ink layer 3 and the resist layer 4 formed on the active film layer 2 are removed. Since the splashing of the coloring agent into the air is thereby prevented, the efficiency of the coloration is improved and the production is economical, as the consumption of more than the need coloring agent is obviated. Since the splashed coloring agent does not stain the other colored parts, the color filter having high saturation is obtd. |
