PLASMA DISPLAY PANEL

Abstract

A plasma display panel includes a first substrate and a second substrate facing each other. A barrier rib together with the first substrate and the second substrate defines a plurality of discharge cells for generating a gas discharge. First discharge electrodes extend in a direction in correspondence with respective discharge cells. Third discharge electrodes are disposed in the barrier rib, extend in the direction and correspond with respective first discharge electrodes in the respective discharge cells. Fourth discharge electrodes are disposed in the barrier rib, extend in the direction, are separated from respective third discharge electrodes and face respective third discharge electrodes with respect to centers of the discharge cells. Address electrodes intersect the direction. Phosphor layers are formed in the discharge cells.
