One of the purposes of the present invention is to provide a resin composition which exhibits excellent coating properties, adhesive properties and moisture permeation resistance and which, when used as a periphery-sealing agent for an organic EL display element, can give an organic EL display element having excellent display performance. Another purpose of the present invention is to provide a periphery-sealing agent for an organic EL display element, which is obtained using the resin composition. The present invention is a resin composition which contains polyisobutylene, a curable resin, a polymerization initiator and fumed silica. The polyisobutylene has a weight average molecular weight of 5000-100,000. The curable resin contains a urethane (meth)acrylate. The content of the urethane (meth)acrylate is 1-30 parts by weight relative to 100 parts by weight of the polyisobutylene. The content of the fumed silica is 1-30 parts by weight relative to 100 parts by weight of the polyisobutylene. |
