The present invention relates to a photosensitive resin composition for color filters of LCDs (Liquid Crystal Displays). Particularly, the photosensitive resin composition performs good photosensitivity in exposure and remains less scum on the unexposed and black matrix of a substrate after development. The color filters made from the composition also exhibit good heat resistance. The composition comprises an alkali-soluble resin (A); a photopolymerizable monomer (B); a photoinitiator (C); an organic solvent (D); and a pigment (E); wherein the photopolymerizable monomer (B) comprises the compound (B-1) having a carboxylic acid group and at least 7 functional groups represented by the following general formula (1), wherein R1 is a hydrogen or a methyl group.
