A plasma display panel is disclosed. The plasma display panel includes a scan electrode and a sustain electrode positioned parallel to each other on a front substrate, an upper dielectric layer positioned on the scan electrode and the sustain electrode, a rear substrate on which an address electrode is positioned to intersect the scan electrode and the sustain electrode, a lower dielectric layer positioned on the address electrode, and a barrier rib positioned between the front substrate and the rear substrate. The barrier rib includes lead (Pb) equal to or less than 1,000 ppm (parts per million). A discharge gas is filled between the front substrate and the rear substrate and includes helium (He) of 9% to 42%.

Plasma display panel

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).
