Abstract
A plasma display panel is disclosed. The plasma display panel includes a front substrate on which a scan electrode and a sustain electrode are positioned, a first black layer positioned between the scan electrode and the front substrate and between the sustain electrode and the front substrate, a rear substrate on which an address electrode is positioned to intersect the scan electrode and the sustain electrode, and a barrier rib that is positioned between the front substrate and the rear substrate to partition a discharge cell. The first black layer includes cobalt (Co) material and ruthenium (Ru) material. The barrier rib including lead (Pb) equal to or less than 1,000 ppm (parts per million).
