Abstract: A display device includes first pixels configured to be positioned in a first pixel area and configured to be connected to first scan lines; first scan stage circuits configured to be positioned in a first peripheral area that is positioned outside the first pixel area and configured to supply first scan signals to the first scan lines; second pixels configured to be positioned in a second pixel area and configured to be connected to second scan lines; and second scan stage circuits configured to be positioned in a second peripheral area that is positioned outside the second pixel area and configured to supply second scan signals to the second scan lines. A gap between adjacent second scan stage circuits is larger than a gap between adjacent first scan stage circuits.

Abstract: Disclosed is a display device, including: a substrate including a pixel area and a peripheral area; pixels provided in the pixel area as a plurality of pixel rows and a plurality of pixel columns; data lines configured to provide a data signal; scan lines configured to provide a scan signal; first power lines configured to provide a power source to the pixel columns; and a second power line connected to the first power lines and disposed in the peripheral area. A scan line connected to an ith pixel row may apply a scan signal to the ith pixel row, and a branched line branched from the scan line may apply an initialization signal to a kth pixel row (k≠i). A branched point of the scan line is disposed between a pixel most adjacent to the second power line of the ith pixel row and the second power line.
