Black column spacer photosensitive resin composition for a black column spacer, a display device, and method of forming the black column spacer

摘要

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, R¹ and R² represent a hydrogen atom or an organic group and at least one of them represents an organic group; R¹ and R² may be bonded to each other to form a cyclic structure or may include a hetero atom bond; R³ represents a single bond or an organic group; R⁴ to R⁹ represent a hydrogen atom, an organic group or the like, however, it is not allowed that both of R⁶ and R⁷ are hydroxyl groups; and R¹⁰ represents a hydrogen atom or an organic group.;COPYRIGHT: (C)2014,JPO&INPIT
