Abstract
The plasma display device includes a plasma display panel having a plurality of discharge cells each having a pair of sustained discharge electrodes and and an address electrode . A voltage is applied to at least one of the sustained discharge electrodes and the address electrode in a sustained discharge period. A sustained discharge voltage is repeatedly applied to the sustained discharge electrodes and . The sustained discharge voltage has a voltage waveform with a rise period (Tr) from a first voltage level to a second voltage level, a sustained period (Tsus) for maintaining the second voltage level, a fall period (Tf) from the second voltage level to the first voltage level and a sustained period (Tg) for maintaining the first voltage level.
