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 photo-sensitive 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.
本发明公开了一种显示面板,包括下部基板、上部基板和图案间隔器,该图案间隔器使得下部基板和上部基板相互间隔一个预定距离,其中,所述图案间隔器是由以下组分组成的光敏树脂组合物制得:(a)一种由以下公式1表示的三嗪基光聚合引发剂;(b)一种碱溶性光聚合反应树脂粘合剂;以及(c)一种聚合物化合物:(其中,R1-R5中的每一个具有如下所定义的相同含义)。本发明还公开了一种用于图案间隔器的光敏树脂组合物,该组合物包括:(a)一种由以下公式1表示的三嗪基光聚合引发剂;(b)一种碱溶性光聚合反应树脂粘合剂;(c)一种聚合物化合物;以及(d)一种溶剂。所述光敏树脂组合物具有高灵敏度和与显影相关的优异性能,并提供具有优异强度、灵敏度、残留特性、膜均匀性、残留膜比率等特性的图案间隔器。
