摘要: A plasma display panel has high definition, high luminance, and low power consumption. In the plasma display panel, the front panel is provided thereon with display electrodes, a dielectric layer, and a protective layer. The display electrodes are formed on the front glass substrate. The dielectric layer coats the display electrodes, and the protective layer is formed on the dielectric layer. The rear panel is provided thereon with address electrodes and barrier ribs for partitioning the discharge space in the direction crossing to the display electrodes. The front and rear panels are opposed to each other with a discharge space therebetween filled with a discharge gas. The protective layer on the dielectric layer includes an underlying film, and aggregated particles adhered on the underlying film, the aggregated particles being formed by aggregating crystal grains of magnesium oxide. The underlying film contains metal oxides composed of at least two oxides selected from magnesium oxide, calcium oxide, strontium oxide, and barium oxide. According to an X-ray diffraction analysis of the surface of the underlying film, in a specific plane direction, the metal oxides have a diffraction angle peak between the minimum and maximum diffraction angles of simple substances of the oxides composing the metal oxides.

摘要: Protective layer of front plate of the plasma display panel is formed of base protective layer and particle layer. Base protective layer is a thin film of metal oxide containing at least one of magnesium oxide, strontium oxide, calcium oxide, and barium oxide. Particle layer is formed in a manner that single-crystal particles of magnesium oxide having a peak of emission intensity at 200-300 nm two times or higher than another peak of emission intensity at 300-550 nm in the emission spectrum in cathode luminescence emission are stuck on base protective layer. The panel driving circuit drives the panel with a subfield structure in which the subfields are temporally disposed so that magnitude of luminance weight has monotonous decrease from a subfield where the all-cell initializing operation is performed to a subfield where the next all-cell initializing operation is performed.

摘要: “Discharge delay” and “dependence of discharge delay on temperatures” are solved by improving a protective layer, thus a PDP can be driven at a low voltage. Furthermore, the PDP can display excellent images by suppressing “dependence of discharge delay on space charges.” Liquid-phase magnesium alkoxide (Mg(OR)2) or acetylacetone magnesium ate whose purity is 99.95% or more is prepared, and is hydrolyzed by adding a small amount of acids to the solution. Thus, a gel of magnesium hydroxide that is a magnesium oxide precursor is formed. Burning the gel in atmosphere at 700° C. or more produces powder containing MgO particles 16a-16d having the NaCl crystal structure with (100) and (111) crystal faces or with (100), (110) and (111) crystal faces. By pasting the powder on a dielectric layer 7 or a surface layer 8, the MgO powder 16 is formed so as to serve as the protective layer.
