To provide a composition for sealing an organic light-emitting element that can form an organic layer with excellent plasma resistance after curing, and an organic light-emitting display device including the organic layer formed therewith.SOLUTION: A composition for sealing an organic light-emitting element includes a cation polymerizable compound with a vinyl group, an allyl group, or a vinyl ether group, and a photoacid generator. The cation polymerizable compound is contained by 95 to 99.9 parts by mass in 100 parts by mass of the composition for sealing the organic light-emitting element on the solid content basis.SELECTED DRAWING: None 【課題】硬化後に耐プラズマ性に優れた有機層を形成することができる有機発光素子封止用組成物、およびこれにより形成された有機層を含む有機発光表示装置を提供する。【解決手段】ビニル基、アリル基、またはビニルエーテル基を有するカチオン重合性化合物と、光酸発生剤と、を含む有機発光素子封止用組成物であって、前記カチオン重合性化合物は、固形分基準で前記有機発光素子封止用組成物１００質量部中に、９５〜９９．９質量部の含有量で含まれる、有機発光素子封止用組成物。【選択図】なし
