ABSTRACT:
The invention provides a plasma display panel having an improved light emission contrast. The plasma display panel includes a plurality of discharge sustaining electrode pairs X.sub.n and Y.sub.n each comprising discharge sustaining electrodes x'.sub.n and x.sub.n, and y.sub.n and y'.sub.n, respectively, which are electrically isolated from each other and which extend in a direction along the scanning lines. The plasma display panel also includes discharging cells in which a discharge occurs within a region limited between the discharge sustaining electrodes x.sub.n and y.sub.n in the first and second priming periods, small-width erasing periods, and writing periods. The black-level intensity can be reduced without causing an increase in the power dissipation and a significant decrease in the normal light emission intensity. Thus, the light emission contrast is improved to a great extent without having to increase the maximum light emission intensity.
