Abstract

A plasma display panel. A first substrate and a second substrate are provided opposing one another with a predetermined gap therebetween. Address electrodes are formed on the second substrate. Barrier ribs are mounted between the first substrate and the second substrate, the barrier ribs defining a plurality of discharge cells and a plurality of non-discharge regions. Phosphor layers are formed within each of the discharge cells. Discharge sustain electrodes are formed on the first substrate. The non-discharge regions are formed in areas encompassed by discharge cell abscissas and ordinates that pass through centers of each of the discharge cells. Further, each of the discharge cells is formed such that ends thereof increasingly decrease in width along a direction the discharge sustain electrodes are formed as a distance from a center of the discharge cells is increased along a direction the address electrodes are formed.
