Abstract:
1. A display device comprising: a semiconductor layer over a substrate; a gate insulating film over the semiconductor layer; a gate electrode, a gate wiring and a capacitor wiring over the gate insulating film; an interlayer insulating film over the gate electrode, the gate wiring and the capacitor wiring; and a pixel electrode over the interlayer insulating film, wherein the pixel electrode is electrically connected to the semiconductor layer, wherein the capacitor wiring includes a first layer and a second layer over the first layer, wherein the first layer is formed over and in contact with a same insulating film as the gate insulating film, and the second layer is formed from a same material as the gate wiring, wherein a storage capacitor is formed from a portion of the semiconductor layer, the insulating film and the capacitor wiring, and wherein the display device is configured to be driven at a frame frequency of 120 Hz or more.
