Abstract: A display device includes a substrate comprising a display area and a non-display area, a light emitting element layer disposed on the display area of the substrate, a counter substrate facing the substrate, a low refractive layer disposed on a surface of the counter substrate, a first capping layer disposed on a surface of the low refractive layer, a second capping layer disposed on a surface of the first capping layer, a spacer layer disposed on a surface of the second capping layer, a first coupling member between the substrate and the counter substrate, and coupling the substrate to the counter substrate, and a second coupling member disposed on side surfaces of the substrate and the counter substrate, and coupling the substrate to the counter substrate. The first coupling member extends to the spacer layer. The first coupling member contains a first moisture absorbent.

Abstract: A display device includes a substrate, a low refractive index layer disposed on the substrate, a first capping layer disposed on the low refractive index layer and directly contacting an upper surface of the low refractive index layer, a second capping layer disposed on the first capping layer, and a wavelength conversion layer disposed on the second capping layer and having a refractive index higher than a refractive index of the low refractive index layer, wherein a nitrogen atomic ratio of the first capping layer is different from a nitrogen atomic ratio of the second capping layer.
