| 1. A plasma display device comprising:
a plurality of first electrodes;
a first transistor having a first terminal electrically connected to a first power supply for supplying a first voltage;
a second transistor having a first terminal electrically connected to a second terminal of the first transistor and a second
terminal electrically connected to the plurality of first electrodes;
a third transistor having a first terminal electrically connected to the plurality of first electrodes;
a fourth transistor having a first terminal electrically connected to a second terminal of the third transistor and a second
terminal electrically connected to a second power supply for supplying a second voltage;
a first capacitor configured to be charged with a third voltage, the first capacitor having a first terminal connected to
the first power supply;
a second capacitor configured to be charged with a fourth voltage, the second capacitor having a first terminal connected
to a second terminal of the first capacitor and a second terminal electrically connected to the second power supply;
a charge path including a first inductor electrically connected between the plurality of first electrodes and a node corresponding
to a contact point between the first capacitor and the second capacitor, the charge path being adapted to increase a voltage
of the plurality of first electrodes;
a charge voltage sustaining path electrically connected between the second terminal of the third transistor and the node,
the charge voltage sustaining path being adapted to sustain the voltage of the plurality of first electrodes at a fifth voltage;
a discharge path including a second inductor electrically connected between the plurality of first electrodes and the node,
the discharge path being adapted to decrease the voltage of the plurality of first electrodes; and
a discharge voltage sustaining path electrically connected between the node and the first terminal of the second transistor,
the discharge voltage sustaining path being adapted to sustain the voltage of the plurality of first electrodes at a sixth
voltage.
