Abstract: A display device includes a first base member having a first light-emitting area, a second light-emitting area, and a non-light-emitting area between the first and second light-emitting areas; a second base member on the first base member; a first color filter on a first surface of the second base member that faces the first base member and overlapping with the first light-emitting area; a second color filter on the first surface of the second base member and overlapping with the second light-emitting area; a color pattern on the first surface of the second base member, between the first and second color filters, and overlapping with the non-light-emitting area; a light-shielding member on the color pattern and overlapping with the non-light-emitting area; and a first wavelength conversion pattern on the second color filter and including a first wavelength shifter.

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.
