Claim:
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 in the second electrode layer so that at least a part thereof overlaps the semiconductor film and the first electrode layer in a plan view, wherein the source electrode is electrically connected to the scanning signal line, and wherein a wiring electrically connects between the light shielding film and the source electrode, and extends in a direction that intersects the scanning signal line.
