Abstract
A display device includes a light-emitting-element layer including a plurality of light-emitting elements each including a first electrode, a functional layer, and a second electrode. The plurality of light-emitting elements are formed to emit lights in different colors. A nanoparticle layer is provided on a surface of the first electrode toward a light-emitting layer, and contains metal oxide nanoparticles that are electrically conductive.
