Abstract
A display device includes a plurality of pixels, wherein a first pixel of the plurality of pixels includes: a scan line extending in a first direction; a data line extending in a second direction intersecting the first direction; a switching thin film transistor (TFT) connected to the scan line and the data line; a driving TFT connected to the switching TFT and comprising a driving gate electrode; a storage capacitor comprising the driving gate electrode as a first electrode and a second electrode arranged above the first electrode and overlapping the first electrode; a horizontal driving voltage line extending from the second electrode in the first direction; and a vertical driving voltage line extending from the second electrode in the second direction, wherein the horizontal driving voltage line, the vertical driving voltage line, and the data line are arranged over a same layer.
