PURPOSE:To improve smoothness, heat resistance, water resistance, and light resistance of a color filter by forming a pattern colored in optional color by dyeing inside of fine pores in an activated film layer comprising activated alumina or activated silica which has been formed on a transparent substrate, and forming an overcoated layer having no affinity with the dye on the pattern. CONSTITUTION:An activated film layer comprising activated alumina and/or activated silica is formed on a transparent substrate, which is colored by dyeing the inside of fine pores in the activated film layer with a dye. Then, dot pattern, stripe pattern, or other pattern are formed on the same plane of the activated film layer in an optional color. Further, an overcoated layer having no affinity with the dye is formed thereon preventing revaporization of dye molecules which have been captured in the fine pores of the activated film layer, preventing simultaneously contamination of the film layer by unnecessary materials. |
