METHOD FOR PRODUCING ADDITIVE SOFT MOLD FOR FORMATION OF BARRIER RIBS OF PLASMA DISPLAY PANEL AND METHOD FOR FORMING BARRIER RIBS USING THE SAME

摘要

PURPOSE: A method for producing an additive soft mold and a method for forming barrier ribs are provided to prevent the camber or damage on a substrate and achieve improved uniformity of height of barrier ribs, while allowing for an ease of removal of mold. CONSTITUTION: A method for producing an additive soft mold for formation of barrier ribs of a plasma display panel, comprises a first step of depositing a photoresist on the surface of a rear surface substrate(50); a second step of forming a basic mold frame by forming photoresist patterns through the use of a photomask where barrier rib patterns are formed; a third step of injecting a rubber material in a solution state into the basic mold frame; a fourth step of solidifying the rubber material; a fifth step of separating the solidified rubber material from the basic mold frame; and a sixth step of forming a through hole at the rear surface of the rubber material which is solidified and separated.
