Abstract: A display device includes an active pattern disposed on a substrate, a first transistor, a first scan line, a first power voltage line, a first electrode pattern and an organic light-emitting layer disposed on the substrate. The first transistor includes a first gate electrode disposed in a first overlapping area of the active pattern where the first gate electrode overlaps the active pattern. The first scan line is disposed adjacent to the first gate electrode. The first power voltage line includes a first electrode portion and a second electrode portion. The first electrode portion overlaps the first gate electrode. The second electrode portion extends from the first electrode portion in a direction crossing the first scan line and overlaps the first scan line.
