The invention relates to a pigment dispersion liquid and colored photosensitive resin composition containing the same. The pigment dispersion liquid of the invention comprising an acrylic resin having a copolymer of specific multiple monomers, and the colored photosensitive resin composition containing the same have excellent physical properties such as optical density, viscosity stability and surface roughness. Besides, the invention may form a cured film with excellent adhesion. In turn, after a development step, display devices such as liquid crystal displays and organic light-emitting diodes made from the above-mentioned pigment dispersion liquid and the colored photosensitive resin composition containing the same are significantly reduce residues as residues of the pigment dispersion liquid around a black pattern. Therefore, compared with the prior art, it has excellent durability, life characteristics and reliability.
