Abstract: A display device includes a display region including light emitting elements; a first inorganic insulating layer covering the light emitting elements; a first organic insulating layer on the first inorganic insulating layer; a second organic insulating layer on the first organic insulating layer; a third organic insulating layer on the second organic insulating layer; and a second inorganic insulating layer on the third organic insulating layer. Edges of the first to third organic insulating layers are between edges of the first and second inorganic insulating layers and an edge of the display region; the edge of the second organic insulating layer is between the edge of the first organic insulating layer and the edge of the display region; and the edge of the third organic insulating layer is between the edges of the first and second inorganic insulating layers and the edge of the second organic insulating layer.

Abstract: An organic electroluminescence display device has a barrier structure that is placed on an upper electrode. The barrier structure has a first organic sealing layer disposed between a first inorganic sealing layer and a second inorganic sealing layer. The first organic sealing layer is divided by the second inorganic sealing layer with respect to each of a plurality of partial areas that form a display area in a plan view and is thicker than a bank having a shape that rises upward.
