ABSTRACT:
In a gas discharge display element according to the present invention, two pairs of electrodes are arranged in a discharge space of a display cell and one of the electrode pairs which forms a first discharge space between the first electrodes is driven such that discharge having a memory function and capable of being memory-driven is produced during a time in which light emission of the display cell is sustained. The other electrode pair is driven with a voltage pulse having duration smaller than that of the driving voltage pulse for the first electrode pair such that discharge a is obtained in the other space defined between the electrodes of the other electrode pair using the discharge in the first space as a seed discharge. The duration of the drive pulse for the second electrode pair preferably terminates before the discharge current is reduced due to the formation of a wall charge.
