A plasma display device is provided to reduce the number of driving voltage sources by using a common voltage source for supplying sustain pulse voltage, setup bias voltage, setdown pulse voltage, and scan pulse voltage. A plasma display device includes a plasma display panel and a scan driving unit using a common voltage source for supplying sustain pulse voltage, setup bias voltage, setdown pulse voltage, and scan pulse voltage among plural driving voltages supplied to a scan electrode(Y) of the plasma display panel. The scan driving unit comprises a sustain pulse/setup bias/setdown pulse/scan pulse common voltage source(Vs) having one grounded end; a sustain pulse/setup bias supply unit(51) connected between the scan electrode and the common voltage source to supply the sustain pulse voltage and setup bias voltage; a setdown pulse/scan pulse supply unit(53) connected between the scan electrode and the sustain pulse/setup bias supply unit to supply the setdown pulse and the scan pulse voltage to the scan electrode; and a first switch(S1) installed between the sustain pulse/setup bias supply unit and the setdown pulse/scan pulse supply unit. |
