ABSTRACT:
A black matrix composition includes about 40 parts by weight of a pigment dispersion, about 0.1 to about 1.0 part by weight of a photoinitiator, about 5 to about 20 parts by weight of a photo-polymerizable monomer, about 5 to about 20 parts by weight of a binder resin including an acryl-based copolymer containing fluorine and having a hydroxyl group combined with a side chain of the acryl-based copolymer, about 0.1 to about 0.5 part by weight of epoxy-based monomer containing fluorine and about 35 to about 55 parts by weight of a solvent. A black matrix pattern formed of the black matrix minimizes an ink bleed, thereby improving color property of a liquid crystal display device to which the black matrix pattern is applied.
