Beschreibung
Zusammenfassung:	The present invention provides a photosensitive resin composition for forming a black column spacer which can form a smooth film without causing wrinkles, a black column spacer formed by using the composition, a display device comprising the black column spacer, and a method for forming a black column spacer by using the composition. A photosensitive resin composition comprises (A) an alkali-soluble resin, (B) a photopolymerizable monomer, (C) a photopolymerization initiator, and (D) a light blocking agent, in which the (B) photopolymerizable monomer comprises (B1) a polyfunctional monomer having 4 or more functional groups, and (B2) a bifunctional monomer and/or trifunctional monomer.
