Abstract: A sealing film includes a first inorganic layer that has, in a surface thereof, a convex portion corresponding to an upper surface of an element layer, a second inorganic layer that covers the first inorganic layer, and an organic layer disposed between these layers. 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 surrounding the element layer. The flat area includes an outer peripheral area on an outer end of the first inorganic layer, and an inner peripheral area between the outer peripheral area and the recurved area. The organic layer has an end in the outer peripheral area, has another portion in the recurved area, and avoids the inner peripheral area. A part of the second inorganic layer contacts the first inorganic layer in the inner peripheral area.
