Abstract
In an alternating current discharge type plasma display panel (PDP) a plurality of parallel barrier walls are formed on a top surface of a back substrate of the PDP and barrier walls are disposed corresponding to cross-points of X electrodes and Y electrodes on a front substrate of the PDP. A structure includes a plurality of discharge cells between the adjacent barrier walls having smaller width corresponding to the X and Y electrodes for forming a large first space, a plurality of non-discharge cells each between the adjacent discharge cells for forming a small second space served as a gas channel between the adjacent discharge cells, and a junction between one discharge cell and the adjacent non-discharge cell, such that energy released from a gas discharge in the discharge cells is concentrated within the discharge cells for increasing discharge efficiency.
