Abstract:
1. A plasma display device comprising: a pair of substrates arranged at a distance so as to face each other; barrier ribs arranged between said pair of substrates for forming a space between said pair of substrates; an electrode pair arranged over at least one facing side of said pair of substrates; a discharge gas sealed in the space formed by said barrier ribs for generating ultraviolet light as a result of electric discharge upon application of a voltage to said electrode pair; and a phosphor layer containing a phosphor for emitting light as a result of excitation by said ultraviolet light formed over at least one of the facing sides of the pair of substrates and wall surfaces of said barrier ribs in the space, wherein the phosphor contains a Eu (wherein M1 is at least one element selected from the group consisting of Sr and Ba; M2 is at least one element selected from the group consisting of Mg and Zn; and x indicates the mole fraction of the component M1 and e indicates the mole fraction of Eu respectively satisfy the following conditions: 0<x<1 and 0.001≦e≦0.2).
