Method of manufacturing soft mold for shaping barrier rib, method of manufacturing barrier rib and lower panel, and plasma display panel

摘要

Provided are a method of manufacturing a soft mold for shaping a barrier rib, a method of manufacturing a barrier rib and a lower panel, and a plasma display panel (PDP). The method of manufacturing the soft mold includes: providing a metal mold (150) on which a barrier rib pattern is formed by alternating concave portions and convex portions; disposing a polymer sheet (180') opposite the metal mold (150); pressurizingly transferring the metal mold (150) into the polymer sheet (180') to form the soft mold (180) having a surface on which an inverted image of the barrier rib pattern is formed; and releasing the soft mold (180) from the metal mold (150). In this method, a fine barrier rib pattern sufficient for a high-resolution PDP can be accurately formed, and the manufacturing process of the PDP can be simplified.
