Summary:PROBLEM TO BE SOLVED: To provide a highly-reliable organic electroluminescent device.SOLUTION: An organic electroluminescent device 1 comprises an inorganic barrier film 4 of at least one layer, an organic electroluminescent element 5 of at least one layer, and a sealing part. The inorganic barrier film 4 is formed so as to come into contact with a flexible base material 2 or an organic resin film 3 of at least one layer formed on the base material 2. The organic electroluminescent element 5 is formed on the inorganic barrier film 4, and includes an anode 51, an organic layer 52 including an organic light-emitting layer, and a cathode 53. The sealing part includes at least one of a flexible sealing film 8 and a sealing film 6, and shields at least one organic electroluminescent element 5 from outside air. A formation surface of the inorganic barrier film 4 is held so that the inorganic barrier film can maintain a state in which a compression stress is applied. 【課題】信頼性の高い有機エレクトロルミネッセンスデバイスを提供する。【解決手段】有機エレクトロルミネッセンスデバイス1は、少なくとも一層の無機バリア膜4と、少なくとも一つの有機エレクトロルミネッセンス素子5と、封止部と、を備えている。無機バリア膜4は、可撓性の基材2、または、基材2上に形成された少なくとも一層の有機樹脂膜3に接するように形成されている。有機エレクトロルミネッセンス素子5は、無機バリア膜4上に形成され、陽極51、有機発光層を含む有機層52、及び、陰極53を含んでいる。封止部は、可撓性の封止フィルム8と封止膜6との少なくとも一方を有し、少なくとも一つの有機エレクトロルミネッセンス素子5を外気から遮蔽する。無機バリア膜4は、圧縮応力がかけられた状態を維持するように、その形成面が保持されている。【選択図】図1
