Abstract
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%.
