Patent ID: 8207672

Claim:
A plasma display panel, comprising, in a structure of a plate structure on a side exposed to a discharge space filled with discharge gas: a first layer formed on a dielectric layer and having a discharge protection function; a second layer formed on the first layer to protect the first layer from exposure to air; and a third layer of a powder formed on the second layer for discharge stabilization, the third layer being exposed to the discharge space, wherein the first, second, and third layers are formed in a vacuum manufacturing process, wherein, upon the vacuum manufacturing process, the powder of the third layer has a layer of a material having a low reactive property with respect to components of air that is formed so as to cover a powder core of the third layer, the powder core containing at least one crystal powder selected from CaO, and SrO, and wherein at least a part of the second layer and at least a part of the low reactive layer are removed by an aging discharge such that portions of the first layer, the second layer, the third layer and the powder core are exposed to the discharge space.
