Abstract

A photoresist composition includes a coloring agent, a binder resin, a cross-linker, a photo-polymerization initiator and a solvent. The coloring agent includes an anthraquinone-based dye and a pigment. A color filter formed from the photoresist composition has a relatively greater light-transmittance. Thus, a contrast of a display apparatus having the color filter may be improved.
