Abstract
A display device includes an electrode layer including a first electrode and a second electrode that are spaced apart from each other and disposed on a substrate, a light emitting element between the first electrode and the second electrode, and a capping layer disposed on the light emitting element and including at least one low refractive layer and at least one high refractive layer that are alternately disposed. The capping layer includes a first low refractive layer on the electrode layer and the light emitting element, a first high refractive layer on the first low refractive layer, and a second low refractive layer on the first high refractive layer. A thickness of the first low refractive layer is greater than a thickness of the second low refractive layer.
