    • When a discharge start voltage takes a normal value under the normal temperature, priming discharge starts at a time t1. In this case, at a time t3 that is later than the time t1 by a predetermined time t, a sustain driver control signal Ssud2 is raised to put a sustain electrode into the floating state to stop the priming discharge. When the discharge start voltage takes a higher value than usual under the high temperature, the priming discharge starts at a time t2. In this case, at a time t4 that is later than the time t2 by the predetermined time t, the sustain driver control signal Ssud2 is lowered to put the sustain electrode into the floating state to stop the priming discharge. With such a configuration, provided is a plasma display device capable of implementing excellent and stable display quality while maintaining constant, even if a discharge start voltage varies, the charge state in display cells after a priming period, and a drive method for such a plasma display device.
