A potential across an output terminal (OUT) is applied to a node N2 through a transistor (Tr66) even when a potential across a node N1 is higher than a power source voltage Vdd due to a bootstrap effect. Accordingly, the potentials between the drain and the source electrodes are not higher than the power source voltage Vdd for both a transistor (Tr62) and the transistor (Tr66). This allows circuit designing without setting the withstand voltage for the transistor over the power source voltage Vdd.
