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 ; and a step for dyeing the photosensitive film into any desired color .
