摘要：A phosphor in which water adsorption onto the surface of a blue phosphor is inhibited, luminance degradation and chromaticity shift of the phosphor is decreased, or discharge characteristics thereof is improved, and a plasma display device using the phosphor. In phosphor layers used for a plasma display, selectively coating at least the vicinity of the sides of planes of mirror symmetry containing Ba atoms in a blue phosphor with an oxide or a fluorine-containing oxide inhibits water adsorption onto the surface of the blue phosphor, decreases luminance degradation and chromaticity shift of a phosphor, or improves discharge characteristics thereof. <IMAGE>
