Patent ID: 7449281

Claim:
A photosensitive resin composition for a black matrix comprising: (A) an alkali-soluble resin; (B) a photopolymerizable monomer; (C) a photoinitiator; (D) a solvent; and (E) a black pigment; wherein said alkali-soluble resin (A) comprises a functional group having a general formula (a-1) wherein each of R is independently H, linear or branch alkyl of C1-C5, phenyl or halogen; wherein the viscosity of said photosensitive resin composition for the black matrix is 0.5-4.0 cps at 25° C. and the solid content of said photosensitive resin composition is 5-17.5 wt %; wherein said solvent (D) has a saturated vapor pressure below 4.5 mmHg at 20° C.; wherein the amount of pigment (E) is 60-300 parts by weight, based on 100 parts by weight of the alkali-soluble resin (A).
