ABSTRACT:
A plasma display panel includes a front panel having a dielectric layer. The dielectric layer of the front panel includes a first dielectric layer and a second dielectric layer disposed on the first dielectric layer. The gas permeability of the second dielectric layer is in the range of 0% to 1%. The second dielectric layer may be formed by heating the surface of the first dielectric layer to thermally metamorphose or transubstantiate the first dielectric layer to a limited depth from the surface the first dielectric layer.
