Abstract:
An organic EL apparatus includes a substrate, an organic EL element that is disposed on the substrate, and a sealing layer that seals the organic light emission element by covering, and the sealing layer is a multilayer body which includes a first sealing layer, a buffer layer, and a second sealing layer respectively having different functions and being sequentially stacked from the organic EL element side. The second sealing layer is mainly made of silicon oxynitride, and includes an inner layer, an intermediate layer, and an outer layer being sequentially stacked on the organic EL element side. Stress of the intermediate layer is equal to or less than stress of the inner layer, and stress of the outer layer is greater than the stress of the inner layer.
