A plasma display device and a driving method thereof are provided to decrease the number of voltage sources by generating a VscL voltage without using an additional voltage source. A scan electrode driving circuit(410A) includes a reset driver(411), a sustain driver(412), a scan driver(413A), a scan circuit(414), and a transistor(Ypn). The sustain driver includes transistors(Ys,Yg). The reset driver includes a diode(Dset), transistors(Yrr,Yfr), and a zener diode(ZD). The scan driver includes a transistor(YscL), capacitors(C1,C2,Csc), and diodes(Dsc,Dg,Dc). The scan circuit includes first and second input terminals and an output terminal. During an address period, the scan circuit selectively supplies voltages from the first and second input terminals to Y electrodes. The zener diode is connected between a drain of the transistor(Yfr) and the Y electrode of a panel capacitor(Cp).
