Method of forming barrier rib and discharge cell for plasma display panel

Abstract

A method of forming barrier ribs for a plasma display panel comprising the steps of: forming an uncured barrier rib material layer on a glass substrates; rolling on said barrier rib material layer a roller having an intaglio recessed pattern corresponding to a desired pattern for the barrier ribs to be formed, so that the freestanding structures of the rib material corresponding to the barrier ribs; and drying and firing the barrier rib material shaped into the freestanding structures, whereby the barrier ribs for partitioning discharge cells are formed on the glass substrate. A phosphor can be filled in the discharge cells by rolling a roller having groove or recessed pattern corresponding the barrier rib pattern on the phosphor material laminated on the substrate. A phosphor material sheet used to form discharge cells on the substrate and manufacturing method thereof are also provided.
