A plasma display device is provided. The plasma display device includes a plasma display panel (PDP) including an upper substrate, on which first and second electrodes are formed, and a lower substrate, on which a third electrode is formed; and a driving unit applying a sustain signal to the first and second electrodes, wherein a negative voltage signal and a positive voltage signal are applied to the first and second electrodes, respectively, after a number of sustain discharges caused by the sustain signal. Therefore, it is possible to efficiently accumulate space charges on each electrode and thus to address the problems associated with a shortage of wall charges such as a misdischarge and a dark discharge.
