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.
Claims26
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.
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.
