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.
