Abstract
A low-cost capacitive load drive circuit, in which a reference voltage, a first voltage, and a second voltage are supplied to a capacitive load, and a plasma display apparatus using it, have been disclosed. The capacitive load drive circuit comprises a reference voltage switch the breakdown voltage of which is properly adjusted, a first switch, a reference voltage phase adjusting circuit, and a first phase adjusting circuit, and malfunctions due to the difference in switching characteristics can be prevented from occurring even when devices of different breakdown voltages are used.
