1. A display apparatus comprising:
a substrate including an opening area, a display area, and a non-display area, the display area surrounding the opening area, and the non-display area being between the opening area and the display area; and
a display element in the display area and including a first electrode, an emission layer, and a second electrode that are sequentially stacked,
wherein the second electrode extends from the display area to the non-display area and includes a second electrode hole defined by an edge of the second electrode that faces and surrounds the opening area, and
a first distance from a center of the opening area to a first portion of the edge of the second electrode is different from a second distance from the center of the opening area to a second portion of the edge of the second electrode, wherein the first distance and the second distance are measured along a same plane that is parallel to a display surface of the display apparatus.
