Abstract: A display device includes a pixel electrode including silver, a pixel-defining film on the pixel electrode and exposing the pixel electrode, a barrier layer on the pixel electrode and the pixel-defining film and including a low-resistance area and a high-resistance area which has a higher resistance than the low-resistance area, an emission layer on the barrier layer, and a common electrode on the emission layer. The low-resistance area of the barrier layer overlaps with the pixel electrode, and the high-resistance area of the barrier layer overlaps with the pixel-defining film.
