Abstract: A display panel includes a first panel region (FPR) including (n−1)-th and n-th pixel rows ((n−1)PR and nPR), and a second panel region (SPR) dividing the nPR to propagate an optical signal. The display panel includes a circuit element layer (CEL) and a display element layer (DEL). The CEL includes a signal line (SL), a pixel driving circuit (PDC), and first to third regions. The SL and the PDC are in the first region. The second region (SR) corresponds to the SPR. The SL and the PDC are not in the SR. The third region (TR) corresponds to the SPR and is along a periphery of the SR. The SL is in the TR, and includes an (n−1)-th scan line ((n−1)SL) connected to the (n−1)PR, an n-th reset line (nRL) connected to the nPR, and a first row connection line in the TR and connecting the (n−1)SL and the nRL.

Abstract: An organic light-emitting display includes a first pixel adjacent to a second pixel and a plurality of driving voltage lines to apply driving voltages to the first pixel and the second pixel. The driving voltage lines extend in a first direction crossing the first pixel and the second pixel and a second direction crossing the first direction. Each of the first and second pixels includes a first driving transistor and a second driving transistor that are symmetrical to each other with respect to a boundary between the first pixel and the second pixel, and a first compensation transistor and a second compensation transistor that are asymmetrical to each other with respect to the boundary.
