Claim Text:
1. A display device comprising: a substrate; a pixel provided on the substrate; a pixel transistor provided in the pixel; an image signal line supplying an image signal to the pixel transistor; a scanning signal line that supplying a control signal to the pixel transistor; and an output transistor provided on the substrate and outputting the control signal to the scanning signal line, wherein the output transistor includes a gate electrode that is provided in a first electrode layer; a semiconductor film that is disposed above the gate electrode via an insulating layer; a drain electrode that is provided in a second electrode layer located over the semiconductor film and is in contact with a part of an upper surface of the semiconductor film; a source electrode that is provided in the second electrode layer over the semiconductor film and is in contact with a part of the upper surface of the semiconductor film; and a light shielding film that is provided so that at least a part thereof overlaps the semiconductor film and the gate electrode in a plan view, wherein the drain electrode is electrically connected to the scanning signal line, and wherein the light shielding film is electrically connected to the drain electrode and formed between the drain electrode and the scanning signal line.
