Plasma display panel having improved efficiency

A plasma display panel, comprising:

• a first substrate;
• a plurality of pairs of a first electrode and a second electrode formed on the first substrate extending parallel with each other, the first electrode and the second electrode generating a sustain discharge, and the first electrode and the second electrode each including at least one recessed portion and at least one projection portion such that the recessed portions and the projection portions of both electrodes face each other;
• a second substrate on a side of the first substrate on which the first electrode and the second electrode are formed such that a discharge space is interposed between the first substrate and the second substrate;
• a plurality of address electrodes formed on the second substrate and facing the first substrate;
• barrier ribs partitioning the discharge space between the first substrate and the second substrate into a plurality of discharge cells;
• and
• a fluorescent substance formed in each of the discharge cells,
• wherein the plasma panel display satisfies 180≦(A+B)+P×0.1≦240 wherein A is a distance between opposite recessed portions of a pair of the first electrode and the second electrode, B is a distance between opposite projection portions of a pair of the first electrode and the second electrode, P is gas pressure of discharge gas in the discharge space.
