Abstract: PROBLEM TO BE SOLVED: To improve displaying quality without generating a writing defect and an erasing defect by executing a step making a discharge current flow in a direction from a scanning electrode group to a data electrode group and a step making a discharge current flow in the direction from a data electrode group to a scanning electrode group in all discharge cells. SOLUTION: A lead terminal part 13 of a scanning electrode and a lead terminal part 14 of a maintaining electrode are formed in a part of very small area in a longitudinal direction of a gas discharging type display device 1 along the both end sides of a glass substrate 2 and a lead terminal part of a data electrode is formed on the front surface of another glass substrate 11. Consequently, a part having an extremely small area becomes an invalid display area and an valid area 19 is made large. A step making a discharge current flow in a direction from a scanning electrode group to a data electrode group and a step making a discharge current flow in a direction from a data electrode group to a scanning electrode group are executed in all discharge cells. Consequently, in all discharge cells, a wall electric charge and a spacial electric charge are regularly replenished.
