It is aimed to reduce the area of an output circuit in a capacitive load driving circuit capable of high voltage output, such as a PDP scan driver for driving a plasma display panel. To achieve this, there are provided an arbitrary number of N-type MOS transistors 001, 002, . . . , and 003 including grounded sources and gates receiving a control signal, diodes 004, 005, . . . , and 006 paired with the N-type MOS transistors 001, 002, . . . , and 003, respectively, and including cathodes connected to drains of the N-type MOS transistors 001, 002, . . . , and 003 and anode, all connected to a first node 044, the number of diodes being the same as the number of N-type MOS transistors, and a first P-type MOS transistor 015 having a drain connected to the first node 044, a gate receiving a control signal and a source connected to a high voltage source.
