Patent ID: 7576490

Claim:
A plasma display panel (PDP) comprising: a first substrate on a front side of the PDP; a second substrate on a rear side opposing the first substrate; a plurality of address electrodes disposed between the first substrate and the second substrate; a first dielectric layer disposed between the first substrate and the second substrate, wherein the plurality of address electrodes are buried between the first dielectric layer and the second substrate; a plurality of barrier ribs disposed between the first dielectric layer and the first substrate to define discharge spaces; a phosphor layer disposed in at least part of the discharge spaces; a plurality of display electrodes disposed between the first substrate and the first dielectric layer; a second dielectric layer disposed between the first substrate and the second substrate, wherein the plurality of display electrodes are buried between the second dielectric layer and the first substrate; and a protective layer disposed between the second dielectric layer and the second substrate, wherein the first substrate comprises at least one transition metal oxide selected from the group consisting of oxides of cobalt (Co), nickel (Ni), iron (Fe), manganese (Mn), chromium (Cr), and vanadium (V), and further comprises at least one rare earth metal oxide selected from the group consisting of oxides of praseodymium (Pr), neodymium (Nd), samarium (Sm), dysprosium (Dy), and holmium (Ho), and wherein the weight ratio of the at least one transition metal oxide to the at least one rare earth metal oxide being from about 0.5 to about 2.
