光敏树脂组合物、使用该光敏树脂组合物制造薄膜晶体管基板的方法和制造共电极基板的方法
摘要：
一种用于有机层图样的光敏树脂组合物，包括：约100重量份的基于丙烯酰基的共聚物，以及约5重量份至约100重量份的1，2－醌重氮化合物。基于丙烯酰基的共聚物可通过使下列物质共聚来制备：以基于丙烯酰基的共聚物总重量为基准，重量百分比约5％至约60％的基于羧酸异冰片酯的化合物，重量百分比约10％至约30％的带有环氧基团的不饱和化合物，重量百分比约20％至约40％的基于烯烃的不饱和化合物，以及重量百分比约10％至约40％的选自不饱和羧酸、不饱和羧酸酐、及其混合物的其中之一。还提供了利用该光敏树脂组合物制造TFT基板和共电极基板的方法。有利地，有机层图样具有山形结构，该山形结构具有改善的局部平整度而没有凹入和凸起结构。
摘要（英）：

A photosensitive resin composition for an organic layer pattern includes about 100 parts by weight of an acryl-based copolymer and about 5 to about 100 parts by weight of a 1,2-quinonediazide compound. The acryl-based copolymer is prepared by copolymerizing about 5 to about 60 percent by weight of an isobonyl carboxylate-based compound based on a total weight of the acryl-based copolymer, about 10 to about 30 percent by weight of an unsaturated compound carrying an epoxy group, about 20 to about 40 percent by weight of an olefin-based unsaturated compound, and about 10 to about 40 percent by weight of one selected from unsaturated carboxylic acid, unsaturated carboxylic acid anhydride, and a mixture thereof. Methods of manufacturing a TFT substrate and a common electrode substrate using the photosensitive resin composition are also provided. Advantageously, the organic layer pattern may have a mountain structure having an improved local flatness without concave and convex structures.
