1. A display device comprising:
a base;
a light emitting element on the base;
a capping layer on the light emitting element;
a thin-film encapsulation layer comprising 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 comprises two sub-inorganic layers having different refractive indices.
