ABSTRACT:
A plasma display panel. A pair of substrates has a transparent front surface and is disposed to leave a discharge space therebetween. A plurality of barrier ribs is 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 is disposed on the substrates to discharge in the discharge spaces partitioned by the barrier ribs. A phosphor layer is 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. A discharge gas is filled in the discharge spaces, wherein the green phosphor layer comprises from 10 to 70% by weight of a first green phosphor selected from the group consisting of Zn2SiO4:Mn, (Zn, A)2SiO4;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.aAl2O3:Mn (where a is from 1 to 23), LaMgAlxOy: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 ReBO3:Tb (where Re is at least one rare earth element selected from the group consisting of Sc, Y, La, Ce, and Gd), and wherein the discharge gas comprises at least 6% by weight of Xe based on the total weight of the discharge gas.
