Abstract:
1. A plasma display panel comprising: a front plate; and a rear plate arranged so as to be opposed to the front plate, wherein the front plate has a display electrode, a dielectric layer to cover the display electrode, and a protective layer to cover the dielectric layer, the protective layer has a luminescence peak in a wavelength ranging from not less than 350 nm to not more than 550 nm under irradiation of light having a wavelength of 146 nm, the protective layer further has a luminescence peak in a wavelength ranging from not less than 350 nm to not more than 550 nm under irradiation of light having a wavelength of 173 nm, and a ratio between a peak intensity of luminescence under the light having the wavelength of 146 nm and a peak intensity of luminescence under the light having the wavelength of 173 nm falls within a range from more than 3.0 to not more than 7.0.
