Abstract
A display device includes: an organic layer including a light-emitting layer, the light-emitting layer including an organic light-emitting material; a reflective layer configured to reflect light generated at the light-emitting layer; a first electrode that is transparent; a second electrode that is transparent; and an optical adjustment layer configured to adjust an optical distance between the reflective layer and the second electrode. The reflective layer, the optical adjustment layer, the first electrode, the organic layer, and the second electrode are arranged in order. A reflectance of a first interface between the organic layer and the first electrode and a reflectance of a second interface between the organic layer and the second electrode are each 11% or less.
