Abstract
A display device includes a first reflective electrode disposed on a surface of a substrate, a second reflective electrode spaced apart from the first reflective electrode and disposed on the surface of the substrate, and a light emitting element disposed between the first reflective electrode and the second reflective electrode. The first reflective electrode includes first surface irregularities disposed on a top surface of the first reflective electrode. The second reflective electrode includes second surface irregularities disposed on a top surface of the second reflective electrode.
