Display and it's driving method

A display device comprising:

• a plurality of first electrodes arranged in a first direction;
• a plurality of second electrodes arranged in said first direction so as to be paired with said plurality of first electrodes respectively;
• a plurality of third electrodes arranged in a second direction crossing said first direction;
• a plurality of discharge cells provided at the intersections of said plurality of first electrodes, said plurality of second electrodes, and said plurality of third electrodes;
• a first voltage applying circuit for periodically applying a first pulse voltage to each of the first electrodes;
• a second voltage applying circuit for periodically applying, in a light emission period in each of fields set for each of the second electrodes, a second pulse voltage having a phase different from that of said first pulse voltage to the second electrode;
• and
• a pulse applying circuit for periodically applying, when all of the plurality of discharge cells connected to each of the second electrodes or the discharge cells whose number is not less than a predetermined number do not emit light in the light emission period in each of the fields set for the second electrode, a pulse voltage having the same phase as that of said first pulse voltage in place of said second pulse voltage to the second electrode in the light emission period.
