Each of the magnesium oxide particles (16a) includes halogen atoms at and in a vicinity of the surface thereof. The magnesium oxide particles (16a) are manufactured such that the halogen atoms exist particularly at the surface of each of magnesium oxide particles (16a) through to a depth of 4 nm or less toward the core of each of the magnesium oxide particles (16a).

摘要： A plasma display device is provided in which deterioration in brightness of phosphor layers can be avoided. The plasma display device includes a plasma display panel in which a plurality of discharge cells in one color or in a plurality of colors are arranged and phosphor layers are arranged so as to correspond to the discharge cells in colors and in which light is emitted by exciting the phosphor layers with ultraviolet rays. The phosphor layers include blue phosphor, the blue phosphor being composed of an alkaline-earth metal aluminate phosphor containing at least one element selected from the group consisting of Mo and W. The addition of hexavalent ions (Mo, W) in the blue phosphor allows the elimination of oxygen defects in the vicinity of a layer containing Ba atoms (Ba—O layer), the suppression of adsorption of water to the surface of the blue phosphor and the improvement of deterioration in brightness and a change in chromaticity for the respective phosphors and discharge characteristics.
