PHOTOCURABLE RESIN COMPOSITION FOR SEALING ORGANIC EL DEVICE

摘要

PURPOSE: A photocurable resin composition for sealing an organic EL device is provided to surely control the generation and growth of a dark sport, to seal the organic EL device without bad effects, and to maintain high transmittance. CONSTITUTION: A photocurable resin composition for sealing an organic EL device comprises: an epoxy resin having two or more glycidyl groups and molecular weight of 200~7000; the epoxy resin having one or more glycidyl groups and molecular weight of 20000~100000; potential photoacid catalyst generating acid; and a silane coupling agent containing the glycidyl group. The potential photoacid catalyst is included in amount of 0.1~10 parts by weight based on the total parts by weight of the epoxy resin.
