Abstract: A display device includes a first substrate, an organic light emitting element on the first substrate and including a first electrode, an organic light emitting layer, and a second electrode, a pixel defining layer surrounding the first electrode, a thin film encapsulation layer, and a capping layer on the thin film encapsulation layer. The capping layer may include two reflective interfaces adjacent the light emission or pixel area spaced apart from one another in a plane view. The reflective interfaces may include a boundary between high and low refractive index materials and/or a reflective layer.
