A display device comprising a plurality of pixels, at least one of the pixels includes:
- a light emitting element;
- a drive transistor configured to supply a drive current to the light emitting element;
- wherein the drive transistor includes a first channel region being a portion of a semiconductor layer, a first gate electrode, and an electrically-conductive layer, wherein the first channel region is formed on a first insulating layer, and the electrically-conductive layer is formed between the first insulating layer and a substrate;
- a write transistor configured to transfer a pixel voltage corresponding to a luminance intensity of the light emitting element, wherein the write transistor includes a second channel region being a portion of the semiconductor layer and a second gate electrode, wherein the second channel region is formed on the first insulating layer;
- a first metal wiring in contact with the semiconductor layer via a first contact region;
- and
- a second metal wiring in contact with the semiconductor layer via a second contact region, the first channel region being a part of a current path between the first contact region and the second contact region,
- wherein the first gate electrode overlaps with a part of the semiconductor layer within the current path in a planer view, and
- a substantially entire portion of the first gate electrode overlaps with the electrically conductive layer in the planer view, and
- at least a portion of the second gate electrode does not overlap with any electrically-conductive layers between the first insulating layer and the substrate in the planer view.
