PROBLEM TO BE SOLVED: To increase contrast of a plasma display panel, by weakening preliminary discharge that decreases electric charges accumulated on a dielectric material and a phosphor nearby an electrode in a cell, and to decrease circuit load, by decreasing the instantaneously flowing current. SOLUTION: Erasure of the electric charges on the dielectric material and on the phosphor and generation of space charges are carried out by each weak discharge, with a first erase pulse 6 applied to a Y electrode which slowly rises up to a voltage for repeated discharges, with a priming pulse 3 applied to an X electrode, which slowly rises up to a voltage that exceeds the discharge start voltage, and then with a second erase pulse 7 applied to the Y electrode, which slowly rises up to a voltage for repetitive discharge and thereby suppresses light emission.
