Abstract: The organic electroluminescence display device has a circuit board, an element layer which contains an organic electrode luminescence film and a positive electrode and a negative electrode sandwiching the organic electroluminescence film and which is formed on the circuit board, and a sealing film sealing the element layer. The sealing film contains an inorganic layer covering the element layer and an organic layer formed between a part of the element layer and a part of the inorganic layer. The upper surface of the element layer has an inorganic contact area contacting the inorganic layer and an organic contact area contacting the organic layer. The organic contact area is a hollow in the upper surface of the element layer. The area of the upper surface of the organic layer is smaller than the area of the lower surface contacting the inner surface of the hollow.

Abstract: A bank layer includes projecting portions swollen toward in a thickness direction of a first substrate in an adhesion area. A multi-barrier includes a portion, in which a organic barrier is not disposed, on an upper side of the projecting portions. Therefore, it is possible to obtain, in the adhesion area, a portion in which a first inorganic barrier layer and a second inorganic barrier layer directly come in contact with each other. In an organic EL display device including the multi-barrier formed of an organic material and an inorganic material, it is possible to prevent two facing substrates from being separated from each other.
