Abstract
A plasma display device includes a plasma display panel provided with plural discharge cells each having discharge gas, a pair of sustain electrodes which generate sustain discharge, and a phosphor, and a driving circuit which applies a sustain pulse voltage between the pair of sustain electrodes for generating the sustain discharge. The sustain pulse voltage is formed of a first portion having a main portion of a first voltage Vp and a second portion succeeding the first portion in time and having a main portion of a second voltage Vs higher than the first voltage Vp, the sustain discharge is formed of a pre-discharge and a main discharge succeeding the pre-discharge in time, and the first voltage Vp is selected to satisfy Vpmin≦Vp<Vs, where Vpmin is a minimum of the first voltage Vp which stabilizes the sustain discharge.
