Abstract

See full text

A display device includes a substrate, a switching element on the substrate, a pixel electrode disposed on the switching element and connected to the switching element, a light emitting layer on the pixel electrode, a common electrode on the light emitting layer, and a sealing portion on the common electrode. The sealing portion includes an organic layer, and at least one first composite inorganic layer disposed between the organic layer and the common electrode. The at least one first composite inorganic layer includes a first inorganic layer between the common electrode and the organic layer, and a second inorganic layer between the first inorganic layer and the organic layer. A refractive index of the first inorganic layer and a refractive index of the second inorganic layer are different from each other, and the first inorganic layer and the second inorganic layer contact each other.
