Abstract

A Plasma Display Panel includes a front panel having a display electrode and a dielectric layer formed on a glass substrate; and a rear panel having an electrode, a barrier rib, and a phosphor layer formed on a substrate. The front panel and the rear panel are disposed facing each other and sealed together at peripheries thereof with discharge space provided therebetween. The display electrode has at least a metal bus electrode including a metal electrode layer containing silver and a glass material, and a black layer containing a black material and a glass material. The glass material of the metal electrode layer and the black layer includes bismuth oxide. An undercut amount of the metal bus electrode is 25 μm or more.

Claims

1. A plasma display panel comprising:

a front panel including a display electrode and a dielectric layer formed on a glass substrate; and

a rear panel including an electrode, a barrier rib, and a phosphor layer formed on a substrate;

the front panel and the rear panel being disposed facing each other and sealed together at peripheries thereof with discharge space provided therebetween,

wherein the display electrode has at least a metal bus electrode including a metal electrode layer containing silver and a glass material, and a black layer containing a black material and a glass material;

the glass material of the metal electrode layer and the black layer includes bismuth oxide; and

an undercut amount of the metal bus electrode is 25 μ

m or more.

2. The plasma display panel of claim 1, wherein an edge curl amount of the metal bus electrode is 70% or less with respect to a film thickness of the metal bus electrode.

3. The plasma display panel of claim 1, wherein the black layer contains at least one of cobalt (Co), nickel (Ni), copper (Cu), oxide of cobalt (Co), oxide of nickel (Ni), and oxide of copper (Cu).
