Patent ID: 8179043

Claim:
A plasma display panel, comprising: a front panel including display electrodes, a dielectric layer, and a protective layer which are formed on a glass substrate; and a rear panel including electrodes, barrier ribs, and phosphor layers all of which are formed on a substrate, wherein the front panel and the rear panel confront each other, and peripheries thereof are sealed to form a discharge space therebetween, the dielectric layer contains Bi 2 O 3 and at least CuO and CoO, and a total content expressed in mole % of CuO and CoO falls within a range from 0.03% to 0.3%, the dielectric layer contains at least two kinds of R 2 O, where R is selected from the group consisting of Li, Na, and K, one kind of the R 2 O is K 2 O, where R is selected from the group consisting of Li, Na, and K and a content expressed in mole % of K 2 O is greater than a total amount of contents of Li 2 O and Na 2 O.
