Abstract
A photosensitive resin composition for a black matrix and a black matrix formed with the same are provided. The photosensitive resin composition for a black matrix includes a solvent 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., and the first solvent, the second solvent, and the third solvent are an aliphatic compound and use at least one solvent composition selected from a group consisting of alkyl ester, alkyl ketone, alkyl ether, and alkyl alcohol, and thus a uniform thin film having no surface defect can be obtained, and the photosensitive resin composition has an excellent process property while securing a high light shielding property and thus a black matrix pattern having a few defect can be obtained, and is thus useful for a liquid crystal display.
