Abstract
A display device includes a substrate, a first electrode on the substrate, a pixel defining layer on the substrate, the pixel defining layer having an opening exposing the first electrode, a metal layer on the pixel defining layer, a light emission layer on the first electrode exposed by the opening, and a second electrode on the light emission layer in the opening. The metal layer contacts the second electrode.
