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.
Claims4
A circuit substrate comprising:
- a first transistor comprising:
- a first gate electrode;
- a first insulating film over the first gate electrode;
- an oxide semiconductor film over the first insulating film;
- and
- a first metal and a second metal over the oxide semiconductor film, the first metal and the second metal being electrically connected to the oxide semiconductor film;
- a second transistor comprising:
- a semiconductor film including silicon;
- a second insulating film over the semiconductor film and under the first gate electrode;
- a second gate electrode over the second insulating film;
- and
- a third metal and a fourth metal electrically connected to the semiconductor film;
- and
- an interlayer film located over the first metal and the second metal,
- wherein the interlayer film is sandwiched between the third metal and the second insulating film and between the fourth metal and the second insulating film, and
- wherein a conductive layer is disposed under the second insulating film and overlaps the first gate electrode in a plane view.
