Zusammenfassung:	To provide a photocurable resin composition as a visibility enhancing resin to be sealed between a liquid crystal panel and a protective substrate, which has small shrinkage by curing, thereby less likely causes warpage, and has excellent heat resistance.SOLUTION: The photocurable resin composition comprises a polyisoprene polyfunctional (meth)acrylate oligomer, a monofunctional (meth)acrylate monomer, an alicyclic resin that is solid at normal temperature, an alicyclic ester compound that is liquid at normal temperature, and a photopolymerization initiator. The total compounding amount of the alicyclic resin and the alicyclic ester compound is 30 to 50 wt.% with respect to the whole solid content of the composition.SELECTED DRAWING: None 【課題】液晶パネルと保護基材との間に封入される視認性向上樹脂で、硬化収縮が小さいため反りが発生しにくく、また耐熱性に非常に優れる光硬化性樹脂組成物を提供する。【解決手段】ポリイソプレン多官能（メタ）アクリレートオリゴマーと、単官能（メタ）アクリレートモノマーと、常温で固体の脂環族樹脂と、常温で液体の脂環族エステル系化合物と、光重合開始剤と、を含み、前記脂環族樹脂と脂環族エステル系化合物の配合量の合計が組成物固形分全体に対し３０〜５０重量％であることを特徴とする光硬化性樹脂組成物である。【選択図】なし
