Abstract:
1. A method of manufacturing rear plate barrier ribs for a Plasma Display Panel (PDP) comprising the steps of: forming a thick film for barrier ribs by coating barrier rib forming paste, which has a wetting angle to a mold less than 90° and a viscosity in usage state less than 20000 cP and includes thermosetting and/or photosensitive binder component, on a glass or metal substrate (or, glass or metal lower plate); positioning a mold, in which a barrier rib shape is imprinted, above the thick film so that the paste is infiltrated into grooves of the mold by means of the capillary phenomenon, and then curing the infiltrated paste; and releasing the mold from the cured barrier ribs and then sintering the barrier ribs.
