Abstract:
A plasma display device comprising:a plasma display panel having a pair of opposing base plates and a plurality of discharge cells formed between said pair of opposing base plates, each of said plurality of discharge cells having a pair of discharge sustain electrodes disposed on one of said pair of opposing base plates and an address electrode disposed on another of said pair of opposing base plates; and a driving circuit for driving said plurality of discharge cells, said driving circuit being configured such that at least one of said pair of discharge sustain electrodes is supplied with a pulse driving voltage within a period of light emission of a corresponding one of said plurality of discharge cells, an address electrode of at least one of said plurality of discharge cells is supplied with a driving voltage within said period of light emission, said driving voltage having a waveform including a portion varying to a voltage level Va in synchronism with variation from a first voltage level to a second voltage level of said pulse driving voltage and then varying to a voltage level Vb before said pulse driving voltage varies from said second voltage level to said first voltage level, an absolute value of said voltage level Vb not being greater than an absolute value of half said voltage level Va.
