A semiconductor device is provided, which includes a switch having a first transistor and a logic circuit having an output terminal. The logic circuit includes a bootstrap circuit having at least one second transistor. The bootstrap circuit is electrically connected to the output terminal. The first transistor and the second transistor have the same conductivity type. Each of the first transistor and the second transistor includes an oxide semiconductor layer including a channel formation region and a pair of gate electrodes with the oxide semiconductor layer provided therebetween. |
