Abstract:
An object is to provide a photosensitive resin composition for color filters, configured to be able to form a high-luminance color layer with excellent heat resistance and light resistance. Disclosed is a photosensitive resin composition for color filters including the dye dispersion liquid, the dye dispersion liquid including a dye dispersed by a dispersant in a solvent, wherein the dye is a dye having a sulfonic acid group; the dispersant is a graft copolymer having an amine number of 30 mg KOH/g or more and including copolymerizable components that contain a specific monomer having a tertiary amine and a specific polymerizable oligomer; the solvent is a solvent having a solubility of the dye of 0.2 g/100 g solvent or less at 23° C.; and the tertiary amine of the dispersant and the sulfonic acid group of the dye form a micelle.
