PROBLEM TO BE SOLVED: To facilitate writing discharge, maintaining discharge, and erase discharge, to eliminate the generation of faulty writing and erase failure, and to improve the quality of display by setting an overall discharge operation period before a train of displaying operation periods and by conducting image display while repeating this series of periods. SOLUTION: A group of scanning electrodes, 3-1 to 3-n, a group of maintaining electrodes, 4-1 to 4-n, and a group of data electrodes, 10-1, to 10-n, are respectively connected to a scanning electrode driving circuit 16, a maintaining electrode driving circuit 17, and a data electrode driving circuit 18 to be driven. An overall discharge operation period is set before each train of displaying operation periods composed from at least one displaying operation period to conduct picture image display using this combination as one unit. Thus, irrespective of image display, writing discharges and maintaining discharges are generated in all discharge cells during the overall discharge operation period to regularly supply wall charge and space charge to all discharge cells. As a result, writing discharge, maintaining discharge and erase discharge become liable to occur.
