Plasma display panel

A plasma display panel comprising:

• a front substrate;
• a scan electrode and a sustain electrode that are positioned parallel to each other on the front substrate, each of the scan electrode and the sustain electrode having a single-layered structure made from a material different from a transparent material;
• 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 barmier rib that is positioned between the front substrate and the rear substrate and partitions a discharge cell,
• wherein each of the scan electrode and the sustain electrode includes a plurality of line portions crossing the address electrode, at least one connection portion coupling at least two line portions crossing the address electrode, at least one connection portion coupling at least two line portions of the plurality of line portions, and two or more projecting portions, projecting from at least one of the plurality of line portions towards a center of the discharge cell from a to plan point of view of the discharge cell, and
• the barrier rib including lead (Pb) equal to or less than 1,000 ppm, wherein a discharge gas is filled between the front substrate and the rear substrate and includes helium (He) of 9% to 42%, wherein the address electrode includes a Pb content, the Pb content of the address electrode being equal to or less than 1,000 ppm, and wherein the Pb content lowers conductivity, of the address electrode to achieve a corresponding reduction in capacitance.
