Patent ID: 7423376

Claim:
A plasma display device provided with a plasma display panel comprising a plurality of columns of discharge cells having one of a single color and multiple colors, and a phosphor layer disposed in each of the discharge cells, the phosphor layer having a color corresponding to the each discharge cell for emitting light when excited by ultraviolet rays, wherein the phosphor layer includes a green color phosphor comprising a mixture of a phosphor material defined by a general formula of M 1-x Al 12 O 19 :Mn x (where “M” denotes one of Ca, Sr, Eu and Zn) with a relation of 0.01≦x≦0.06, and one of phosphor materials defined by general formulae of (Y 1-a-y Gd a ) (Ga 1-x′ Al x′ ) 3 (BO 3 ) 4 :Tb y with a relation of 0.1≦x′≦1.0, 0.02≦Y≦0.4, 0≦a≦0.9), and (Y 1-a-y Gd a ) (Ga 1-x′ Al x′ ) 3 (BO 3 ) 4 :Ce y , Tb y with relation of 0.1≦x′≦1.0, 0.02≦Y≦0.4, 0≦a≦0.9).
