6. A method for driving a gas electric discharge device having a plurality of cells defining a display screen and each having a first main electrode and a second main electrode arranged in parallel to form an electrode pair and a data electrode crossing the electrode pair, forming three electrode gaps affording a gas electric discharge therebetween, in which two of the three electrodes are covered with a dielectric layer for supporting a wall voltage thereon, the method comprising:
a repeated execution of address preparation for rendering a charge distribution on the display screen to be uniform, addressing for producing a charge distribution in accordance with a content of display and illumination sustainment for generating a gas electric discharge periodically by applying an alternating current,
wherein at least one of the address preparations includes a charge adjustment by applying voltages monotonously rising from first set values to second set values, to at least two of the three electrode gaps in the one cell, thereby to generate a plurality of feeble gas electric discharges successively occurring from voltages between the first set values and the second set values to voltages of the second set values so as to adjust the wall voltages at the at least two of the three electrode gaps in one cell during the monotonously rising of the voltages.
