Beschreibung
Zusammenfassung:	To provide a sealing agent for a display applicable even to a flexible display or a curve-shaped display, more particularly, to provide a sealing agent for a display containing a compound having a specific structure in the molecule, which can achieve both flexibility and low moisture permeability and is useful as a display requiring adhesiveness with an organic film, a flexible display or a sealing agent for a curve-shaped display.SOLUTION: There is provided a sealing agent for a display containing a component (A): a curable compound having three or more reactive functional groups in the molecule, wherein a cured product, obtained by curing the curable compound with a 3000 mJ/cmof UV light by adding 2 mass% of a photoinitiator, has an elastic modulus of 1000 MPa or less and a fracture-point elongation of 10% or more.SELECTED DRAWING: None 【課題】本発明は、フレキシブルディスプレイや湾曲形状のディスプレイにも適用できるディスプレイ用封止剤に関する。より詳細には、分子内に特定の構造を有する化合物を含有するディスプレイ用封止剤に関する。このディスプレイ用封止剤は、柔軟性と低透湿性を両立できるものであり、有機膜との接着性が要求されるディスプレイやフレキシブルディスプレイ、湾曲形状のディスプレイ用封止剤として有用である。【解決手段】成分（Ａ）：分子内に３以上の反応性官能基を有する硬化性化合物であり、２質量％の光開始剤を添加して、紫外線３０００ｍＪ／ｃｍ２で硬化させた硬化物の弾性率が１０００ＭＰａ以下、破断点伸度が１０％以上である硬化性化合物、を含有するディスプレイ用封止剤。【選択図】なし
