Claim Text:
1. A display device, comprising: a plurality of arrayed display pixels, each of the display pixels comprising: a luminescence element that emits light in accordance with a current; a drive transistor that includes a first gate electrode and supplies a current corresponding to a level of a luminance signal to the luminescence element; and a switching transistor that includes a source electrode, a drain electrode, a second gate electrode and a semiconductor layer, the semiconductor layer being faced with the second gate electrode and having, in a channel width direction perpendicular to a channel length direction of the switching transistor, a channel region with a first width and a remainder region with a second width larger than the first width, either the source electrode or the drain electrode being connected to the first gate electrode, both the source electrode and the drain electrode being provided on the semiconductor layer at an interval, and the second gate electrode overlapping, in a plan view, the channel region and the semiconductor layer entirely, and the remainder region at least partially.
