This invention discloses a negative photosensitive resin composition which has excellent properties such as sensitivity, flatness, resolution and residue film rate, and particularly the formation process of white sub-pixels and interlayer insulating films in RGBW(Red, Green, Blue, White) are simultaneously performed, which not only simplify the pattern forming method, but also be effectively used for a display having high brightness and low power consumption. The negative photosensitive resin composition includes an acrylic copolymer; a polyfunctional urethane-based methacrylate compound represented by the following chemical formula (1); a radical photoinitiator; and a solvent, wherein in the chemical formula (1), D is a hydrocarbon group having 1 to 20 carbon atoms, and n and m are each independently an integer of 0 to 2.
