The present invention relates to a pigment dispersion and a colored photosensitive resin composition containing the same. The pigment dispersion comprising an acrylic resin containing a copolymer of the monomers of Chemical Formulas 1 to 5 and the colored photosensitive resin containing the same can form a cured film having excellent physical properties such as optical density, viscosity stability, surface roughness, etc. as well as excellent adhesion. Furthermore, a display device such as LCDs, OLEDs, etc. prepared from the pigment dispersion and the colored photosensitive resin composition containing the same has significantly excellent durability, lifespan characteristics, and reliability compared to a conventional device, as residues, which are pigment dispersion residues, are significantly reduced around a black pattern after a development step.
