Abstract: A display panel includes a substrate having a first area and a second area, a non-display area surrounding the first area and the second area, and a display area surrounding the non-display area, a plurality of display elements arranged in the display area, and a plurality of signal lines electrically connected to the plurality of display elements, wherein the plurality of signal lines includes a first signal line and a second signal line neighboring each other and extending in a first direction, wherein the first signal line bypasses in the non-display area along a first side of the first area, and the second signal line bypasses in the non-display area along a second side of the first area, and wherein the first and second signal lines are asymmetrical with respect to a virtual central line through a center of the first area in the first direction.
