Abstract: A display device includes: a substrate including a display area and a peripheral area positioned outside the display area; a first power supply line positioned in the peripheral area; a first insulating layer positioned on the first power supply line; and a second power supply line positioned on the first insulating layer in the peripheral area. The first power supply line includes a first main wire extending in a first direction and a first sub-wire diverging toward the display area from the first main wire, the second power supply line includes a second main wire extending in the first direction and a second sub-wire diverging toward the display area from the second main wire, the first main wire includes an internal edge positioned near the first sub-wire and an external edge facing the internal edge, and the second main wire does not overlap the internal edge in a plan view.
