PROBLEM TO BE SOLVED: To provide a semiconductor device having a planar transistor using an oxide semiconductor and a capacitative element connected to the transistor.SOLUTION: A semiconductor device has a transistor and a capacitative element. The transistor includes an oxide semiconductor film, a gate insulation film on the oxide semiconductor film, a gate electrode on the gate insulation film, a second insulation film on the gate electrode, a third insulation film on the second insulation film, and a source electrode and a drain electrode which are arranged on the third insulation film and electrically connected with the oxide semiconductor film. The capacitative element includes a first conductive film, a second conductive film and a second insulation film, in which the first conductive film is provided on the same surface with the gate electrode, and the second conductive film is provided on the same surface with the source electrode and the drain electrode, and the second insulation film is provided between the first conductive film and the second conductive film.
