本发明提供一种制成硬化膜时的耐化学品性良好且相对介电常数低的感光性树脂组成物、硬化膜的制造方法、硬化膜、液晶显示装置以及有机EL显示装置。本发明的感光性树脂组成物含有包含以下聚合物的聚合物成分、下述(S)成分、光酸产生剂、溶剂，所述聚合物满足包括具有酸基由酸分解性基所保护的基团的构成单元及具有交联性基的构成单元的聚合物、包含具有酸基由酸分解性基所保护的基团的构成单元的聚合物及包括具有交联性基的构成单元的聚合物的至少一者；并且(S)成分为如下化合物，其包括直链或分支的碳数6~20的脂肪族烃基(可于脂肪族烃基中具有选自-O-、-S-、环状伸烷基及伸芳基中的至少1种基团；其中，于具有2个以上的选自-O-、-S-、环状伸烷基及伸芳基中的基团的情况下，所述2个以上的基团并不邻接)以及具有选自烷氧基矽烷基、嵌段异氰酸酯基、嵌段异硫氰酸酯基、嵌段乙烯酮基、异氰酸酯基、异硫氰酸酯基、硫醇基及恶唑啉基、或者酯基、硫醚基、二硫化物基、醯胺基及胺基甲酸酯基中的至少1种基团的基团，且不具有羧基及醇性羟基，另外，即便与聚合物成分的酸基进行反应，亦不产生羧基及醇性羟基的化合物。;The photosensitive resin composition contains a polymer component which contains a polymer that satisfies one of the followings: a polymer which has a constituent unit having a group wherein an acid group is protected with a acid-decomposable group and having a crosslinkable group, a polymer which has a constituent unit having a group wherein an acid group is protected with a acid-decomposable group and a polymer which has a constituent unit having a crosslinkable group; a component (S); an photoacid generator; a solvent. The component (S) is a compound as follows: a compound having a 6-20C straight chain or branched aliphatic hydrocarbon group (in the aliphatic hydrocarbon group which may have at least one of the groups selected from -O-, -S-, a cyclic alkylene group, and an arylene group, wherein the 2 or more groups are not adjacent when there are 2 or more groups selected from -O-, -S-, a cyclic alkylene group, and an arylene group), and having at least one group selected from an alkoxysilane group, a block isocyanate group, a block isothiocyanate group, a block ketene group, an isocyanate group, an isothiocyanate group, a thiol group and an oxazoline group, or an ester group, a thioether group, a disulfide group, an amide group and an urethane group, and without the carboxyl group and an alcoholic hydroxyl group. In addition, even if the component reacts with the acid group of the polymer component, a carboxyl group and an alcoholic hydroxyl group is not produced. |
