Patent ID: 7408299

Claim:
A plasma display panel comprising a red phosphor layer, a green phosphor layer, and a blue phosphor layer, wherein the thickness of a phosphor layer coated on a barrier rib is satisfied by the following condition: 0.67≦D r ≦0.89, 0.69≦D g ≦0.89, and 0.64≦D b ≦0.84 where D is (S−2L)/S, and D r , D g , and D b respectively represent a red discharge cell D value, a green discharge cell D value and a blue discharge cell D value which are respectively formed with the red phosphor layer, the green phosphor layer and the blue phosphor layer, wherein S is a distance between barrier ribs at half the height of the barrier rib and L is a side thickness of the phosphor layer coated on the barrier rib, wherein the red phosphor layer comprises Y(V,P)O 4 :Eu and (Y,Gd)BO 3 :Eu wherein the barrier rib is on a substrate, the barrier rib having a barrier rib base proximal to the substrate and a barrier rib top distal from the substrate, and wherein a thickness of the barrier rib increases in a direction from the barrier rib top to the barrier rib base.
