Patent ID: 7932675

Claim:
A plasma display panel comprising: a front plate having display electrodes, a dielectric layer, and a protective layer formed on a glass substrate; and a rear plate that has electrodes, barrier ribs, and a phosphor layer formed on a substrate and is disposed opposite to the front plate, wherein peripheries of the front plate and the rear plate are sealed to form a discharge space, the display electrodes contains at least silver, the dielectric layer is configured to include a first dielectric layer that covers the display electrodes and contains bismuth oxide, and a second dielectric layer that covers the first dielectric layer and contains bismuth oxide, wherein the first dielectric layer contains 25% to 40% by weight of bismuth oxide, the thickness of the first dielectric layer is equal to or larger than 5 μm and equal to or smaller than 13 μm, and the ratio of the thickness of the first dielectric layer to the thickness of the display electrodes is larger than 1 and equal to or smaller than 3.
