Beschreibung
Zusammenfassung:	A plasma display panel including a discharge gas for generating ultraviolet light as a result of electric discharge, and a phosphor layer containing a phosphor for emitting light upon excitation by ultraviolet light is provided. The phosphor contains a novel Eu-activated silicate phosphor represented by (CaxM11-x)3-e.M2.Si2O8: Eue. In the formula, 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; x is the mole fraction of the component Ca satisfying the condition of 0
