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.

Abstract: Provided is a display device including: a capacitor having a first electrode, a first insulating film over the first electrode, and a second electrode over the first insulating film; and a first transistor over the capacitor. The first transistor includes the second electrode, a second insulating film over the second electrode, an oxide semiconductor film over the second insulating film, and a first source electrode and a first drain electrode over the oxide semiconductor film. The first source electrode and the first drain electrode are electrically connected to the oxide semiconductor film.
