PROBLEM TO BE SOLVED: To provide a photosensitive colored composition having high sensitivity, a high remaining film ratio and excellent pattern features even when pigment content is high or film thickness is thick, and to provide a color filter using the photosensitive colored composition. SOLUTION: The photosensitive colored composition contains an oxime ester-based photopolymerization initiator (A) having a carbazole nucleus, a transparent resin (B), a photopolymerizable compound (C), and a pigment (D). The color filter includes a filter segment or a black matrix formed of the photosensitive colored composition on a transparent substrate. COPYRIGHT: (C)2011,JPO&INPIT
