Summary:A highly reliable organic electroluminescence device is provided. An organic electroluminescence device (1) includes at least one layer of inorganic barrier film (4), at least one organic electroluminescence element (5), and a sealed portion. The inorganic barrier film (4) is formed to contact to a flexible substrate (2) or at least one layer of organic resin film (3) formed on the substrate (2). The organic electroluminescence 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 sealed portion includes at least one of a flexible sealing film (8) and a sealing membrane (6), and blocks at least one organic electroluminescence element (5) from the air outside. The formed surface of the inorganic barrier film (4) is held to maintain a state in which a compressive stress is applied.
