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 device including: a substrate having a display area and a peripheral area outside the display area; a thin-film transistor disposed in the display area, the thin-film transistor including a semiconductor layer, a gate electrode, a source electrode, and a drain electrode; an organic insulating layer configured to cover the thin-film transistor in the display area and including a first opening located in the peripheral area; and a pattern portion disposed on the substrate to correspond to the first opening, the pattern portion including: a first pattern layer and a second pattern layer at least partially overlapping each other, and an inorganic insulating layer disposed between the first pattern layer and the second pattern layer over the display area and the peripheral area.
