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.
