PROBLEM TO BE SOLVED: To provide the driving method of a PDP(plasma display panel) which reduces optical backgrounds which are to be generated by ionization so as to increase the number of times of ionization without reducing the visual sensitivity of the PDP and, moreover, increases the visual sensitivity of the PDP. SOLUTION: This driving method of the PDP uses preconditioning ionization in respective subfields with reduced optical backgrounds. Moreover, the driving method is applied to an 'address and display synchronism' drive mode in which an ionization pulse IP, address pulses AP and an erase pulse EP are overlapped on a sustaining signal common to all lines of the PDP. The sustaining signal includes at least four levels (L1 to L4) and it is possible that ionization pulses and the erase pulse are overlapped respectively on continual two levels, that is, levels L1 and the level L2.
