PLASMA DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a plasma display device in which efficiency of maintaining discharge is improved by devising a driving method without using a large sized high frequency power supply or the like. SOLUTION: The plasma display device is provided with a plasma display panel which has a plurality of discharging cells having a sustaining discharge electrode pair and a writing electrode. During a light emitting discharge interval, a pulse driving voltage is applied to at least one of the sustaining discharge electrode pair. During a light emitting display interval, a driving voltage is aspplied to the writing electrode in at least one discharge cell among a plurality of discharge cells. The driving voltage has a process in which a change is made to a voltage level Va interlocked with the change from a first voltage level to a second voltage level of the pulse driving voltage to be applied to at least one electrode of the maintaining discharge electrode pair and the absolute value of the voltage of the writing electrode is reduced to equal to or less than the absolute value of Va/2 by the time when the pulse driving voltage changes from the second voltage level to the first voltage level.
