Abstract:
A plasma display panel comprising:a back substrate; a front substrate positioned on the back substrate and forming a space between the facing surfaces of the front substrate and the back substrate; a plurality of barrier ribs positioned in the space for defining a plurality of discharge space groups, each group comprising a first discharge space, a second discharge space and a third discharge space; a first traverse rib positioned in each first discharge space; a second traverse rib positioned in each second discharge space, the transverse length of the second traverse rib being smaller than that of the first traverse rib; a blue-emissive phosphor layer coated on the surfaces of the back substrate, the first traverse ribs, and on the barrier ribs surrounding each first discharge space; a green-emissive phosphor layer coated on the surfaces of the back substrate, the second traverse ribs, and on the barrier ribs surrounding each second discharge space; and a red-emissive phosphor layer coated on the surfaces of the back substrate, and on the barrier ribs surrounding each third discharge space; wherein the coverage of the red-emissive phosphor layer is less than that of the green-emissive phosphor layer and the coverage of the blue-emissive phosphor layer is greater than that of the green-emissive phosphor layer.
