Patent ID: 8822127

Claim:
A photosensitive resin composition for a black matrix comprising a coloring dispersion, a binder resin, a functional monomer having an ethylenically unsaturated bond, a photopolymerization initiator, and solvents, wherein the solvents have a solvent system consisting of 5-30 weight % of a first solvent having a boiling point of 110-159° C., 55-90 weight % of a second solvent having a boiling point of 160-200° C., and 3-15 weight % of a third solvent having a boiling point of 201-280° C., wherein, each of the first solvent, the second solvent, and the third solvent is an aliphatic compound, wherein the third solvent is at least one selected from the group consisting of diethyleneglycolmonoethylether, hexylbutyrate, diethyleneglycol methyletheracetate, diethyleneglycolbutyl methyl ether, tripropylglycoldimethyl ether, triethyleneglycoldimethylether, diethyleneglycolethyletheracetate, diethyleneglycolbutyletheracetate, 3-epoxy-1,2-propanediol, ethyl-4-acetylbutyrate, diethyleneglycolmonobutylether, tripropylglycolmethyl ether, diethyleneglycol, 2-(2-butoxyethoxy)ethylacetate, catechol, triethyleneglycol methylether, diethyleneglycoldibutylether, triethyleneglycol ethylether, diethyleneglycolmonohexylether, triethyleneglycol butyl methyl ether, triethyleneglycolbutylether, tripropylglycol, and tetraethyleneglycoldimethylether; wherein in the composition, a carbon black content, based on an overall solid content, is in the range of 50-85 weight %, and wherein the overall solid content is a sum of components except for the solvents.
