ABSTRACT:
A plasma display panel includes a first substrate, on which discharge sustain electrodes are formed, and an opposing second substrate, on which address electrodes are aligned in a first direction. Barrier ribs between the substrates define a plurality of discharge cells within which phosphor layers are formed. The discharge sustain electrodes have bus electrodes, forming a corresponding pair within each of the discharge cells, and extension electrodes, extending from the bus electrodes into each of the discharge cells to form an opposing pair. Each extension electrode has an end with a further extending portion with a first width 2α and a lesser extending portion with a second width β. A distance between further extending portions defines a first gap, and a distance between lesser extending defines a second gap longer than the first gap. The first and second widths satisfy 1.5≦α/β≦4.
