Abstract:
1. A plasma display panel comprising: a front panel through which light is emitted to the outside of the PDP, a rear panel on which phosphors are disposed, a plurality of transparent electrodes disposed on a front glass substrate, bus electrodes disposed on the transparent electrodes in parallel to the transparent electrodes, a front dielectric layer configured to cover the transparent electrodes and bus electrodes, a protective layer configured to cover the front dielectric layer, and a discharge gas, wherein the protective layer comprises MgO having a first cathode-luminescence spectrum emission peak at a wavelength from about 300 nm to about 370 nm, and a second emission peak at a wavelength from about 600 to about 640 nm, and wherein the intensity ratio of the first emission peak to the second emission peak is from about 1:0.4 to about 1:0.6.
