The first pixel electrode is connected to a first pixel circuit through the first via hole. The second subpixel includes a second pixel definition layer including a second opening exposing a portion of a second pixel electrode corresponding to a second emission portion. The second pixel electrode is connected to a second pixel circuit through the second via hole. A second distance defined as a shortest distance from an inner surface of the second opening to the second via hole is greater than a first distance defined as a shortest distance from an inner surface of the first opening to the first via hole.
