PROBLEM TO BE SOLVED : To provide a photosensitive resin composition from which a black column spacer that gives a sufficient height difference can be formed in a process of carrying out exposure through a halftone mask, and to provide a black column spacer formed by using the composition, a display device having the black column spacer, and a method for forming a black column spacer using the composition.SOLUTION : A composition comprises an alkali-soluble resin, a photopolymerizable monomer, a photopolymerization initiator, a compound expressed by a formula (1), and a light shielding agent. In the formula, Rand Rrepresent a hydrogen atom or an organic group and at least one of them represents an organic group; Rand Rmay be bonded to each other to form a cyclic structure or may include a hetero atom bond; Rrepresents a single bond or an organic group; Rto Rrepresent a hydrogen atom, an organic group or the like, however, it is not allowed that both of Rand Rare hydroxyl groups; and Rrepresents a hydrogen atom or an organic group.
