Abstract: A display device has a display area and a non-display area extending around the display area and includes: a plurality of pixels in the display area, a first voltage line in the display area; and a second voltage line in the non-display area. Each of the pixels includes an electrode pattern connected to the first voltage line, a pixel-defining film on the electrode pattern, an emission layer on the pixel-defining film, and a common electrode on the emission layer. The pixels include first-type pixels in which the common electrode and the electrode pattern are connected through an opening hole formed in the pixel-defining film and exposing part of the electrode pattern and second-type pixels in which the opening hole is not formed and the common electrode and the electrode pattern are not connected. The first-type pixels and the second-type pixels are adjacent to each other.
