Claim 19:
20. A display device comprising:
a base;
a light emitting element on the base;
a thin-film encapsulation layer comprising a first inorganic layer on the light emitting element, a first organic layer on the first inorganic layer, and a second inorganic layer on the first organic layer;
a wavelength conversion pattern on the thin-film encapsulation layer and overlapping the light emitting element;
a capping layer on the wavelength conversion pattern;
a color filter on the capping layer and overlapping the wavelength conversion pattern; and
an upper thin-film encapsulation layer on the color filter and comprising a third inorganic layer, a second organic layer on the third inorganic layer and a fourth inorganic layer on the second organic layer,
wherein the third inorganic layer comprises a first sub-inorganic layer on the color filter and a second sub-inorganic layer on the first sub-inorganic layer, and the first sub-inorganic layer is different in refractive index than the second sub-inorganic layer.
