ABSTRACT:
A photoresist resin composition comprises about 10 to about 35% by weight of an acryl-based copolymer, about 5 to about 10% by weight of a quinone diazide compound, about 55 to about 80% by weight of a solvent, and about 0.01 to about 0.5% by weight of a silane-based surfactant where the weights of each of the acryl-based copolymer, quinone diazide compound, solvent, and silane-based surfactant are based on the total weight of acryl-based copolymer, quinone diazide compound, solvent, and silane-based surfactant. An overcoating layer formed using the photoresist resin composition has improved flatness, and thus defects on a display screen may be prevented and/or reduced.
