    Abstract: A display panel includes a first display area and a second display area. The display panel includes a plurality of first pixel groups in the first display area, a plurality of second pixel groups in the second display area, and a plurality of scan lines connected to the first and second pixel groups. The second display area includes a plurality of light emitting areas in which the second pixel groups are respectively disposed, and a plurality of open areas in which the second pixel groups are not disposed. One of a second pixel group of an n-th row is cut and does not overlap an adjacent open area of the n-th row, and is connected in the second display area to a scan line of a second pixel group of an (n−1)-th row or a scan line of a second pixel group of an (n+1)-th row.

    Abstract: Provided is a scan driver for applying a bias voltage comprising a kth stage that includes an inputter transmitting an input signal to a first node, a stress reliever disposed between the first node and a second node, a carry signal outputter receiving a high-power-supply voltage and a second clock signal and outputting the second clock signal, an output signal outputter receiving the high-power-supply voltage and a third clock signal and outputting the third clock signal, a maintainer transmitting the first clock signal to a third node, and a stabilizer applying a first low-power-supply voltage to the third node and the high-power-supply voltage to the first node. The first and second clock signals selectively toggle between the high-power-supply voltage and the first low-power-supply voltage, the third clock signal selectively toggles between the high-power-supply voltage and a second low-power-supply voltage, and the bias voltage is adjusted as the second low-power-supply voltage varies.
