Driving method of PDP and display device

   
   

A method for driving a PDP is provided in which power loss is reduced and light emission efficiency is improved while applying a voltage pulse train so as to generate display discharge whose number of times corresponds to luminance in cells to be lighted. A drive step of one pulse for generating one time of display discharge includes steps of supplying current to a pair of display electrodes of the cells to be lighted from a drive power source so as to charge capacitance between the display electrodes so that voltage between the display electrodes exceeds display discharge start voltage and cutting off a current path between the display electrode pair and the drive power source at least in a part of a period from start to end of the display discharge.
