Abstract: A display panel includes: a substrate including a first display area and a second display area including a transmission area; a plurality of first display elements arranged in the first display area; a plurality of second display elements arranged in the second display area, the plurality of second display elements each including a pixel electrode and an emission layer; and a pixel defining layer defining an emission area by an opening exposing a central portion of the pixel electrode of each of the plurality of second display elements. In at least one of the plurality of second display elements, a first center of the emission layer and a second center of the emission area do not coincide with each other in a plan view.
