Abstract:
1. A plasma display panel comprising: a front substrate; a rear substrate arranged by a predetermined interval from the front substrate; a plurality of sustain electrodes arranged in parallel with each other on the front substrate; a plurality of data electrodes arranged in a direction perpendicular to the plurality of sustain electrodes on the rear substrate; and a plurality of barrier ribs arranged at a constant interval between the front substrate and the rear substrate to partition discharge cells; wherein each of the sustain electrodes includes: a transparent electrode; and a bus electrode arranged on the transparent electrode, wherein a black layer is formed between the transparent electrode and the bus electrode to enhance contrast such that the black layer covers an entire surface of the front substrate exposed to a non-discharge area between the discharge cells, wherein the bus electrode is formed on an area extending from a part of the black layer formed on the transparent electrode in the discharge cell to a part of the black layer formed on the non-discharge area and wherein the bus electrode contacting the black layer formed on the non-discharge area has a width ranged from (⅛)L to (⅞)L, where L is a length of the bus electrode.
