Patent ID: 8072142

Claim:
A plasma display panel comprising: a front panel including display electrodes, a dielectric layer and a protective layer formed on a front glass substrate; and a rear panel including electrodes, barrier ribs, and phosphor layers formed on a rear substrate, wherein the first panel and the rear panel are disposed facing each other and sealed together at peripheries thereof with discharge space provided therebetween, wherein the display electrodes contain at least silver, wherein the dielectric layer includes a first dielectric layer and a second dielectric layer, the first dielectric layer covering the display electrodes and containing bismuth oxide, and the second dielectric layer covering the first dielectric layer and containing bismuth oxide, wherein a thickness ratio of the second dielectric layer to the first dielectric layer is not less than 1.3 and not more than 7.2, and wherein the first dielectric layer includes not less than 0.1 wt % and not more than 7 wt % of at least one of molybdenum oxide and tungsten oxide.
