Display panel including patterned spacer
Disclosed is a display panel including a lower substrate, upper substrate, and a patterned spacer that causes the lower substrate and upper substrate to be spaced apart from each other by a predetermined distance, wherein the patterned spacer is obtained from a photosensitive resin composition comprising: (a) a triazine-based photopolymerization initiator represented by the following formula 1; (b) an alkali-soluble photo polymerizable reactive resin binder; and (c) a polymerizable compound:(wherein each of R1-R5 has the same meaning as defined herein). A photosensitive resin composition for use in a patterned spacer is also disclosed, the composition comprising: (a) a triazine-based photopolymerization initiator represented by the following formula 1; (b) an alkali-soluble photopolymerizable reactive resin binder; (c) a polymerizable compound; and (d) a solvent. The photosensitive resin composition shows high sensitivity and excellent properties related with development, and provides a patterned spacer having excellent strength, sensitivity, residue characteristics, film uniformity, residual film ratio, etc.
