Abstract
A PDP (Plasma Display Panel) with high luminance and long service life is disclosed. Two substrates are positioned face to face and located at the scanning side and data side, respectively. A reflection layer for reflecting vacuum ultraviolet rays is formed on the surface of one substrate facing the other substrate located on the data side. The reflection layer has a laminate structure made up of alternating layers of two substances each having a particular refractive index. The reflection layer reflects ultraviolet rays reached the substrate on the scanning side toward the other substrate. As a result, the amount of ultraviolet rays to be incident to a phosphor and therefore the luminance of the PDP increases.
