A driver circuit of the present invention includes: a pair of switch elements (P1, N1) connected in series between a ground terminal and a stepped-up voltage VCP application terminal to which a stepped-up voltage VCP is applied; and a clamp element ZD1 connected between a node A between the pair of switch elements and an output terminal T2, the driver circuit driving, according to a voltage signal derived from the node A, an N-channel output transistor Q1 connected between the output terminal T2 and a power supply voltage VCC application terminal to which a power supply voltage VCC is applied. Here, a current control section (IL1, IL2) formed of a resistor and a capacitor that are connected in parallel with each other is inserted in at least one of a current path that connects the node A and the stepped-up voltage VCP application terminal and a current path that connects the node A and the ground terminal.
