According to the present invention, in a driving method for an AC type discharge display device having one pair of discharge electrodes which are opposite to each other to cross through a discharge gas and each of which is constituted by a plurality of line-shaped electrodes, the plurality of line-shaped electrodes of at least one discharge electrode of the one pair of discharge electrodes being covered with a dielectric layer, an AC discharge keeping pulse Vxy to be applied across one pair of discharge electrodes is constituted by a first pulse and a second pulse having a polarity reverse to the polarity of the first pulse and generated next to the first pulse, the first pulse is made a narrow-width pulse having a pulse width set within a time in which a priming effect of charged particles or metastable atoms generated by the first pulse is kept in a discharge space, the second pulse is made a wide-width pulse which is generated before the priming effect obtained by the first pulse is disappeared and within a time being close to the first pulse and also has a pulse width for giving a sufficient time until a discharging is stopped by forming wall charges on the dielectric layer, and the AC discharge keeping pulse constituted by the first and second pulses is continuously applied across the one pair of discharge electrodes to perform a sustain discharging, so that a driving method for an AC type discharge display device which can decrease influence of an ion impact on a discharge electrode or a phosphor can be obtained.
