Abstract: A display device includes a light-emitting element layer that emits light with a luminance controlled for each of a plurality of unit pixels constituting an image, and a sealing layer provided on the light-emitting element layer and including a plurality of layers. The plurality of layers of the sealing layer includes at least an inorganic layer provided on the light-emitting element layer, an organic layer provided on the inorganic layer, and an inorganic layer that is an uppermost layer. A density of the inorganic layer that is the uppermost layer in a thickness direction changes in the thickness direction.

Abstract: The organic electroluminescence display device of an embodiment of the present invention includes a substrate, a plurality of pixels formed on the substrate, and a sealing film that covers the plurality of pixels. The sealing film includes a first barrier layer, a base layer covering the top surface of the first barrier layer, an inter layer locally formed on the top surface of the base layer, and a second barrier layer covering the top surface of the base layer and the top surface of the inter layer. The inter layer is formed so as to cover a step on the top surface of the base layer.

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.
