摘要：
A method of producing color filters comprising:a step for forming a photosensitive film by coating, on a rugged substrate, a mixture of a light-absorbing material which absorbs light and which can be removed with a solvent and a photosensitive material;a step for irradiating light onto the photosensitive film through a predetermined pattern;a step for removing dissolvable portions of the photosensitive film and the light-absorbing material from the photosensitive film which remains on the substrate; anda step for dyeing the photosensitive film into any desired color.
