Display device

A display device comprising:

• a capacitor comprising:
• 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 comprising:
• the second electrode;
• a second insulating film over the second electrode;
• an oxide semiconductor film over the second insulating film;
• a third insulating film over the oxide semiconductor film;
• a third electrode over the third insulating film;
• and
• a first source electrode and a first drain electrode over the third electrode, the first source electrode and the first drain electrode being electrically connected to the oxide semiconductor film.
