Abstract: Provided is a display device including a plurality of pixels at least one of which has a first transistor and a light-emitting element. The first transistor includes a gate electrode, a gate insulating film over the gate electrode, an oxide semiconductor film over the gate insulating film, and a first terminal and a second terminal electrically connected to the semiconductor film. The second terminal is electrically connected to the light-emitting element. A region in which the first terminal overlaps with the gate electrode can be smaller than a region in which the second terminal overlaps with the gate electrode.
