Patent ID: 7456575

Claim:
A plasma display panel, equipped with opposing front and back substrates placed on either side of a discharge space, a plurality of row electrode pairs provided between the front and back substrates, and a plurality of column electrodes provided between the front and back substrates and extending in a direction at right angles to the row electrode pairs to form unit light emission areas in the discharge space at positions respectively corresponding to the intersections with the row electrode pairs, comprising: a discharge gas including 10 or more vol % of xenon and filling the discharge space; and a magnesium oxide layer including magnesium oxide crystals that have a crystalline structure causing a cathode-luminescence emission having a peak within a wavelength range of 200 nm to 300 nm upon excitation by an electron beam, and provided in a position facing the unit light emission areas, wherein the magnesium oxide layer has a structure of lamination of a thin-film magnesium oxide layer and a crystalline magnesium oxide layer including the magnesium oxide crystals.
