Patent ID: 7965041

Claim:
A plasma display panel comprising: a front panel including display electrodes, a dielectric layer, and a protective layer that are formed on a glass substrate; and a rear panel including electrodes, barrier ribs, and phosphor layers that are formed on a substrate, wherein the front panel and the rear panel are faced with each other, and peripheries thereof are sealed to form a discharge space therebetween, wherein the dielectric layer contains Bi 2 O 3 and at least CaO and BaO, and a content expressed in mole % of CaO is greater than that of BaO, wherein 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, wherein one of R 2 O is K 2 O, where R is selected from the group consisting of Li, Na, and K, wherein 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.
