Abstract

A display device includes a base; a light emitting element on the base; a capping layer on the light emitting element; a thin-film encapsulation layer including a first inorganic layer on the capping layer, an organic layer on the first inorganic layer, and a second inorganic layer on the organic layer; and a wavelength conversion pattern on the thin-film encapsulation layer and overlapping the light emitting element, wherein the first inorganic layer includes two sub-inorganic layers having different refractive indices.
