Claim:
A driving method for a plasma display panel having discharge cells serving as pixels formed at respective intersections between a plurality of row electrodes corresponding to display lines, and a plurality of column electrodes arranged across said row electrodes, in which a field of a video signal is constituted by N subfields, and said plasma display panel is driven subfield by subfield such that subfields in each field of which the number is set according to a grayscale level to be displayed are continuously driven to emit light, wherein each of said subfields comprising: an address period for generating a selective erase discharge in each of said discharge cells to set said each of said discharge cells to either one of a light-on discharge cell state and a light-off discharge cell state; and a light emission sustain period for repeating a sustain discharge only in said discharge cells in said light-on discharge cell state for a number of times corresponding to a weight of said subfield, wherein selective erase discharges for one discharge cell comprises a first selective erase discharge executed in the address period of one subfield of said N subfields, and second selective erase discharges respectively executed in the address periods of subfields after said one subfield, said one discharge cell is driven to emit light successively in the light emission sustain periods of subfields from the head subfield to a subfield just before said one sub-field in which said first selective erase discharge is executed, and said second selective erase discharges, excluding those executed in L successive subfields after said one subfield in which said first selective erase discharge is executed, are executed only in address periods of M (M<N−L−1) subfields at predetermined positions from the head subfield, for all of grayscale levels from the lowest grayscale level to each of the grayscale levels; wherein L>2.
