A drive device includes a first gate driver circuit that controls operations of the first transistor by outputting a first control signal to a control terminal of the first transistor; a second gate driver circuit that controls operations of the second transistor so that the first transistor and the second transistor are turned on/off in a complementary manner, by outputting a second control signal to the control terminal of the second transistor; and a first charge pump circuit that applies the first negative power supply voltage to the first negative power supply wiring, by generating the first negative power supply voltage having a polarity opposite to that of the first positive power supply voltage with reference to a potential of the output terminal, based on the first control signal.
