Abstract
A capacitive load circuit and a plasma display apparatus using such a circuit, being able to use a sustain transistor having a voltage rating in accordance with a sustain voltage even when a voltage larger than the sustain voltage is applied to a sustain electrode, have been disclosed, wherein a switch whose one end is connected to a capacitive load is comprised and when a third voltage, whose voltage difference from a second voltage is larger than the voltage difference between a first voltage and the second voltage, is applied to the capacitive load, a fourth voltage is selectively applied to the other end of the switch.
