Abstract
A semiconductor device with high reliability is provided. The semiconductor device includes a first transistor, a second transistor, a capacitor, and first to fourth wirings. The first transistor includes a first gate and a second gate, and one of a source and a drain of the first transistor is connected to the first wiring and the second gate, and the other of the source and the drain is connected to one of a source and a drain of the second transistor and one electrode of the capacitor. A gate of the second transistor is connected to the other electrode of the capacitor, and the other of the source and the drain of the second transistor is electrically connected to the second wiring. The first wiring is supplied with a first potential, and the second wiring is supplied with a second potential and a third potential alternately. The third wiring is connected to the first gate and supplied with a first signal. The fourth wiring is connected to the gate of the second transistor and supplied with a second signal obtained by inverting the first signal.
