Abstract:
1. An organic electroluminescence display device, comprising: a circuit substrate; an element layer that is formed on the circuit substrate with the inclusion of an organic electroluminescence film, and an anode and a cathode which hold the organic electroluminescence film therebetween, and has a concavo-convex shape in an upper surface opposite to the circuit substrate; and a sealing film that seals the element layer, wherein the sealing film includes a first inorganic layer that is disposed on the circuit substrate so as to cover the upper surface of the element layer, and has, in a surface thereof, a convex portion corresponding to the concavo-convex shape of the upper surface, a second inorganic layer that covers the surface of the first inorganic layer, and an organic layer disposed between the first inorganic layer and the second inorganic layer, wherein the surface of the first inorganic layer includes a recurved area changed from an area around the convex portion to the convex portion, and a flat area flattened at a position surrounding the element layer, wherein the flat area includes an outer peripheral area on an outer end of the first inorganic layer, and an inner peripheral area inside of the outer peripheral area, and adjacent to the recurved area, wherein the organic layer has an end in the outer peripheral area, has another portion in the recurved area, and is disposed with the avoidance of the inner peripheral area, and wherein a part of the second inorganic layer is positioned to come in contact with the surface of the first inorganic layer in the inner peripheral area.
