Abstract: The present invention provides a plasma display panel (PDP) capable of simplifying the number of processes, reducing costs for materials, improving an exhausting function and preventing erroneous discharge and cross-talk phenomena between neighboring cells. The present invention provides a plasma display panel (PDP), including: a vertical barrier rib and a horizontal barrier rib, wherein the vertical barrier rib and the horizontal barrier rib form a hexagonal shape to encompass discharge cell region in all directions; a connection barrier rib connecting the vertical barrier rib to the horizontal barrier rib, wherein the connection barrier rib have a groove at a central portion thereof so that a length of the horizontal barrier rib is shorter than a distance between the vertical barrier ribs; and a gas-passing path formed above a top surface of the horizontal barrier rib of which height is lowered with respect to a surface of the vertical barrier rib.

Abstract: Provided is a method for forming barrier ribs of a plasma display panel (PDP), in which the rear substrate is protected from camber and damage occurring in the pressing process, and the mold can be separated easily by manufacturing a soft mold using elastic silicon rubber and forming uniform barrier ribs in a press method using the soft mold. In addition, a method for manufacturing a transparent soft mold is suggested, and uniform barrier ribs are formed by pressing a photosensitive barrier rib paste with the transparent soft mold, exposing them to a particular light source to reduce contact surface between the mold and the paste and thus make the mold separated easily.

Abstract: Provided is a plasma display panel (PDP) manufacturing technology, and more particularly, to a method for manufacturing an additive soft mold forming barrier ribs of a PDP and a method for forming barrier ribs of a PDP that can prevent camber and damage of a glass substrate, produce barrier ribs with uniform height, and make the soft mold separated easily. In this research, an additive soft mold is manufactured using an elastic rubber material, and barrier ribs of a PDP are formed by using the additive soft mold. In particular, the barrier rib paste can be filled by polishing the rear surface of the soft mold and forming an opening, using a squeezer instead of performing a pressing process. When a photopolymerizing photosensitive paste is used as a paste for forming barrier ribs, and it is exposed to UV light, the soft mold can be separated easily from the paste, because the polymer in the paste shrinks due to the polymerization reaction.
