Abstract: A display panel includes: a substrate having a first area, a second area at least partially extending around a periphery of the first area, and a third area at least partially extending around a periphery of the second area; a first pixel portion in a portion of the first area that is adjacent to a boundary between the first area and the second area; and a second pixel portion nearer to a central portion of the first area than the first pixel portion is. A number of sub-pixels in the first pixel portion is less than a number of sub-pixels in the second pixel portion.

Abstract: A display panel includes: a first sub-pixel circuit at a first display area, and including: a first transistor; a storage capacitor; and a second transistor; an organic insulating layer on the first transistor and the second transistor; a first light-emitting diode at the first display area, and electrically connected to the first sub-pixel circuit; a second light-emitting diode at a second display area including a transmission area; a bank layer having a first opening, and a second opening; at least one line overlapping with a first electrode of the first light-emitting diode and the first opening of the bank layer; and a conductive pattern layer at the second display area and overlapping with a first electrode of the second light-emitting diode and the second opening of the bank layer. The conductive pattern layer is located at a same layer as that of the at least one line.
