摘要：
A plasma display device comprises blue phosphor which restricts adsorption of water and hydrocarbon gases to a surface thereof, reduces degradation of luminance and chromaticity change, and improves discharge characteristic. Among phosphor layers used for a plasma display, a blue phosphor layer comprises one of compounds symbolized by Ba1-xMgAl10O17:Eux and Ba1-x-ySryMgAl10O17:Eux, of which phosphor contains 0.2 to 0.8 in number x of Eu atoms, and the Eu atoms comprises 25% to 85% concentration of bivalent Eu ions, and 15% to 75% concentration of trivalent Eu ions.
