▎ 摘　　要

NOVELTY - Photosensitive resin composition comprises binder resin, black colorant comprising graphene oxide, photopolymerizable monomer, photopolymerization initiator, and solvent. USE - Photosensitive resin composition. ADVANTAGE - The photosensitive resin composition minimizes degradation of the optical density, and maintains low dielectric constant with excellent sensitivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following : (1) a method for preparing black pixel defining layer, which involves using the photosensitive resin composition; and (2) a display device, which comprises black pixel barrier layer.
