A semiconductor device includes rectifying elements which are connected in series and has a rectifying function from a first input terminal portion to an output terminal portion; a first wiring and a second wiring, which are connected to a second input terminal portion; and a boosting circuit including a plurality of capacitor elements each having a first electrode, an insulating film, and a second electrode and storing a boosted potential. The plurality of capacitor elements includes a capacitor element in which the first electrode and the second electrode are formed using conductive films, and a capacitor element in which at least the second electrode is formed using a semiconductor film. In the plurality of capacitor elements, at least a capacitor element in a first stage is a capacitor element in which the first electrode and the second electrode are formed using conductive films.
