본 발명의 목적은, 예를 들면 액정 실링제로서 이용했을 때에, 가시광에 대한 경화성이 높고, 또한 액정 오염을 고도로 억제할 수 있는 광경화성 수지 조성물을 제공하는 것이다. 본 발명의 광경화성 수지 조성물은, 분자 내에 에틸렌성 불포화 이중 결합을 갖는 경화성 화합물 A와, 분자 내에 안트라퀴논 골격 또는 싸이오잔톤 골격과, 1 이상의 NHCO기를 갖고, 식(I)로 표시되는 NHCO기 당량이 350g/eq 이하인 화합물 B를 포함한다. NHCO기 당량(g/eq)=분자량/1분자에 포함되는 NHCO기의 수...식(I) The purpose of the present invention is to provide a photocurable resin composition which exhibits high curability with respect to visible light if used, for example, as a liquid crystal sealing agent, and which is capable of highly suppressing liquid crystal contamination. A photocurable resin composition according to the present invention contains: a curable compound A that has an ethylenically unsaturated double bond in each molecule; and a compound B that has one or more NHCO groups and an anthraquinone skeleton or a thioxanthone skeleton in each molecule, while having an NHCO group equivalent represented by formula (I) of 350 g/eq or less. Formula (I): NHCO group equivalent (g/eq) = (molecular weight)/(number of NHCO groups contained in one molecule)
