Abstract
In a plasma display device, a second terminal of a first transistor, whose first terminal is connected to an electrode, is connected to a power source for supplying a first voltage. A first driver is adapted to drive the first transistor to change the voltage of the electrode, and a second driver adapted to sustain the voltage of the electrode substantially at a second voltage differing from the first voltage by intercepting a path between the first transistor and the power source when the voltage of the electrode is changed into the second voltage in a first period, and to change the voltage of the electrode substantially back to the first voltage in a second period. In this way, it is possible to supply two or more voltages having a different voltage level by one power source.
