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.
