To provide a semiconductor device with low power consumption, in a semiconductor device including a differential amplifier to which an input potential and a reference potential are input, a gain stage, and an output stage from which an output potential is output, a potential supplied from the gain stage can be held constant by providing the output stage with a transistor with low leakage current in an off state. As the transistor with low leakage current in an off state, a transistor including an oxide semiconductor layer and a channel formation region included in the oxide semiconductor layer is used. |
