Abstract
A display device according to an embodiment of the disclosure includes a plurality of first electrodes on a substrate, a pixel definition layer between respective ones of the plurality of first electrodes and covering edges of the plurality of first electrodes, an emission layer on the plurality of first electrodes, a metal wiring on the pixel definition layer, and a second electrode on the emission layer and the metal wiring and electrically connected to the metal wiring. The display device can reduce a voltage drop of a common voltage transmitted by the second electrode without reducing a pixel aperture ratio by bringing the metal wiring into contact with the second electrode.
