Abstract: PROBLEM TO BE SOLVED: To prevent quality of an image from being deteriorated by simultaneous resetting of all cells of a plasma display panel. SOLUTION: A field is divided into plural sub-fields, and the sub-fields are composed of a reset period, an address period, and a sustaining conducting period, however, a reset period in at least one sub-field in one field is adopted as a whole reset period to reset all the cells simultaneously, and the other reset periods are adopted as a reset period to reset only the cell which sustaining conducting period directly preceding sustaining conducting period.  For this all reset period, A11 reset pulses PR of a high voltage and a wide pulse width are impressed on all X-electrodes at the same time and all the cells are reset, however, the wall charges of the sustaining conducting cells are erased by impressing a filament line erase pulse PE having an amplitude almost equal to that of a sustaining conducting pulse PS and a pulse width of about 1 μsec to all X-electrodes at the same time.
