Abstract: A display device includes a base, a light emitting element disposed on the base, a capping layer disposed on the light emitting element, a thin-film encapsulation layer which is disposed on the capping layer and includes an inorganic layer at the bottom, and a wavelength conversion pattern which is disposed on the thin-film encapsulation layer and overlaps the light emitting element. The capping layer includes a first sub-capping layer disposed on the light emitting element and a second sub-capping layer disposed between the first sub-capping layer and the inorganic layer, and a refractive index of the second sub-capping layer is greater than a refractive index of the inorganic layer and smaller than a refractive index of the first sub-capping layer.
