A photosensitive resin composition comprising an alkali-soluble resin (A), a polyoxyalkylene polymer (B), an ethylenically unsaturated group-containing compound (C), a photoinitiator (D), a solvent (E), and a black Pigment (F). The alkali-soluble resin (A) includes a resin (A-1) having an unsaturated group, and the resin (A-1) having an unsaturated group is obtained by polymerization of a mixture, and the mixture contains at least a two epoxy group-containing epoxy compound (i), and a compound (ii) having at least one carboxylic acid group and at least one ethylenically unsaturated group; and the unsaturated group-containing resin (A-1) and polyfluorene The weight ratio of the oxyalkylene polymer (B) is in the range of 0.1 to 3.0. The black matrix formed of the photosensitive resin composition has better surface flatness and has better surface resistance stability after heating. |
