Fluorescent substance formation formation manner of the plasma display panel and in the manner which forms the fluorescent substance formation of multiple striped conditions in the substrate inside

摘要

PROBLEM TO BE SOLVED: To uniformly and accurately form phosphor layers by arranging filament-shaped mold composed of a fluorescent material and a synthetic resin between plural parallel ribs prearranged on a base board, and forming the phosphor layers between the ribs by performing baking processing after filling a solvent optionally containing a synthetic resin having compatibility with a resin between the ribs. ;SOLUTION: Filament-shaped molds 54 are obtained by drying phosphor paste for several minutes to several hours at 100°C or less after being molded into a filament shape. The filament-shaped molds 54 for red, green and blue are arranged in order between ribs (r) of a substrate 21 by using support arms 52a, 52b and support bars 57a, 57b. Next, after removing the substrate 21 from a placing stand 51, a mixture (a paste shape) of ethyle cellulose and butyl carbitol acetate is applied to the surface of the substrate 21, and when it is baked at 450°C for 30 minutes after drying, phosphor layers of respective colors of red, green and blue are formed between the ribs.;COPYRIGHT: (C)1999,JPO
