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.

The protective layer is stacked on the insulating layer. The column electrodes are arranged on a surface of the second insulating substrate, which opposes the discharge gas spaces, in a direction perpendicular to the row electrodes. The second insulating layer is stacked on the column electrodes. The phosphors are stacked on the insulating layer at positions corresponding to the pixels, respectively. The ribs are arranged on the row electrodes so as to define the pixels. A method of driving the plasma display is also disclosed.
