Abstract: Adsorption of water by the surface of a blue fluorescent material is suppressed to improve degradation inluminance, change in chromaticity or discharge characteristic of the fluorescent material. In a fluorescent layer used in a plasma display, adsorption of water by the surface of the blue fluorescent material is suppressed, and degradation in luminance, change in chromaticity or discharge characteristic of the fluorescent material is improved by eliminating oxygen defects in the vicinity of a layer (Ba-O layer) containing Ba atoms of the blue fluorescent material.
