Abstract: A display device includes a pixel. The pixel is electrically connected to a first power line, a second power line, and a data line. The pixel includes a first transistor, and a capacitor electrically connected between a gate electrode of the first transistor and an electrode of the first transistor. In a plan view, the data line extends in a second direction. The first power line extends in a first direction intersecting the second direction and overlaps the data line and the gate electrode of the first transistor. The second power line extends in the second direction, overlaps the data line, and overlaps the gate electrode of the first transistor.
