Patent ID: 7759868

Claim:
A plasma display panel equipped with a front substrate and a back substrate which face each other on either side of a discharge space, row electrode pairs and column electrodes which are provided between the front substrate and the back substrate and form unit light emission areas at intersections with each other in the discharge space, and a dielectric layer covering the row electrode pairs, the plasma display panel comprising: a crystalline magnesium oxide layer that includes crystal powder having particle-size distribution in which a crystal of a predetermined particle diameter or larger is included at a predetermined ratio or higher, of powder of a magnesium oxide crystal which has a cathode-luminescence emission having a peak within a wavelength range of 200 nm to 300 nm, and that is provided in an area facing the discharge space between the front substrate and the back substrate, wherein the powder of the magnesium oxide crystal forming the crystalline magnesium oxide layer has particle-size distribution by volume in which a ratio of a crystal of a particle diameter greater than 1.0 μm is 55% or more.
