Patent ID: 6998779

Claim:
A plasma display panel comprising: a pair of substrates having a transparent front surface and disposed to leave a discharge space therebetween; a plurality of barrier ribs disposed on one substrate to partition the discharge space into a plurality of respective green discharge spaces, blue discharge spaces and red discharge spaces; a group of electrodes disposed on the substrates to generate discharge in the discharge spaces partitioned by the barrier ribs; a phosphor layer formed in the discharge spaces, the phosphor layer being a green phosphor layer for the green discharge spaces, a blue phosphor layer for the blue phosphor discharge spaces, and a red phosphor layer for the red discharge spaces; and a discharge gas filled in the discharge space, wherein each green phosphor layer comprises from 10 to 70% by weight of a first green phosphor selected from the group consisting of Zn 2 SiO 4 :Mn, (Zn, A) 2 SiO 4 ;Mn where A is an alkali metal, and mixtures thereof; from 0 to 30% by weight of a second green phosphor selected from the group consisting of (Ba, Sr, Mg)O.aAl 2 O 3 :Mn where a is from 1 to 23, LaMgAl x O y :Tb,Mn where x is from 1 to 14 and y is from 8 to 47, and mixtures thereof; and from 20 to 70% by weight of a third green phosphor selected from the group consisting of ReBO 3 :Tb where Re is at least one rare earth element selected from the group consisting of Sc, Y, La, Ce, and Gd, wherein the discharge gas comprises at least 6% by weight of Xe based on the total weight of the discharge gas.
