Abstract: A display device includes a substrate including a display area and a non-display area, a first power supply line in the non-display area and applying a first supply voltage to the display area, and a driving voltage line which is in the display area and connects the display area to the first power supply line. The first power supply line includes a first sub-power supply line, and a second sub-power supply line which is on the first sub-power supply line. The second sub-power supply line includes a same material as the driving voltage line.
