The present invention relates to a non-solvent type negative photosensitive resin composition, and more particularly, to a non-solvent type negative photosensitive resin composition comprising a urethane-based multifunctional (meth) acrylate, an acrylic monomer and a photopolymerization initiator. The non-solvent type negative photosensitive resin composition according to the present invention is not only excellent in insulation, heat resistance, flatness, light transmittance and chemical resistance, but also improves the field effect mobility and can be patterned. It may be used as an interlayer insulating film of a display, an organic electroluminescent device (OLED), an electro-interactive device (EPD), and the like. |
