Claim:
1. A display device comprising: a display region including a plurality of pixels, each of the plurality of pixels comprises: a thin film transistor; a light emitting element including a pixel electrode connected to a high-potential voltage power supply via the thin film transistor, and a common electrode connected to a low-potential voltage power supply; and a conductive layer below the pixel electrode, the conductive layer connected to the low-potential voltage power supply, the thin film transistor comprises: a semiconductor layer which includes a channel region; a gate electrode over the channel region; a first electrode electrically connected between the semiconductor layer and the pixel electrode and a second electrode electrically connected between the semiconductor layer and the high-potential voltage power supply, wherein the conductive layer includes an overlapped region which overlaps with the pixel electrode, and the first electrode extends between the overlapped region of the conductive layer and the gate electrode.
