Abstract

A display device includes: multiple layers including a display element layer, the multiple layers including a sealing layer for covering the display element layer; and a polarization plate attached to a first layer and a second layer of the multiple layers with an adhesive layer. The multiple layers includes inorganic films and organic films. All of the inorganic films are disposed to avoid an edge area that is at least a part of a peripheral portion of the resin substrate. The polarization plate has an edge above the edge area of the resin substrate. The first layer is disposed to avoid the edge area of the resin substrate. The first layer at an edge has an upper surface sloping downward toward the edge area. The second layer has a portion in the edge area of the resin substrate and between the resin substrate and the adhesive layer.
