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.
Claims6
A PDP (Plasma Display Panel) comprising:
- a pair of glass substrates respectively located at a scanning side and a data side and facing each other with the intermediary of a preselected gas discharge space;
- a phosphor layer formed on at least one of said pair of glass substrates;
- a reflection layer formed on a surface of the other glass substrate facing the one glass substrate for reflecting vacuum ultraviolet (UV) rays, wherein said reflection layer has a laminate structure made up of alternating layers of at least two substrates, each substance having a particular refractive index, and wherein each of the at least two substances has a high transmissivity for vacuum UV rays and high band gap energy.
A method of producing a PDP, comprising the steps of:
- (a) positioning a pair of glass substrates face to face while forming a preselected gas discharge space between said pair of glass substrates;
- (b) forming a phosphor layer on at least one of said pair of glass substrates;
- (c) forming a reflection layer on a surface of the other glass substrate facing the one glass substrate for reflecting UV rays, wherein step (c) further comprises forming a laminate structure made up of alternating layers of at least two substances each having a particular refractive index, and wherein each of the at least two substances has a high transmissivity for vacuum UV rays and high band gap energy.
