<P>PROBLEM TO BE SOLVED: To provide a photosensitive black composition which retains such a sensitivity as to form a cured film while reducing a carbon black content and has a wide development margin, and to provide a black matrix having a very high light blocking effect and a good shape. <P>SOLUTION: The photosensitive black composition contains a carbon black of ≥pH 5 having ≤100 ml/100 g oil absorption of dibutyl phthalate, an ethylenically unsaturated compound and a photopolymerization initiator having a weight reduction rate of ≥30% under the conditions of 230°C and 30 min. A black matrix substrate with the black matrix formed from the photosensitive black composition is provided, and a color filter with filter segments of at least two colors other than black formed on the black matrix substrate is also provided. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
