Abstract In this study, barrier ribs of plasma display panel were formed via capillary molding process. Various types of working molds were prepared by casting liquid polydimethylsiloxane on master molds that were produced from a photoresist film. A thermosetting paste was filled into the cavities of working molds by means of capillary action of paste and was cured prior to removing the molds. The effects of solid loading in the paste, prefiring temperature and type of barrier ribs on the sintering shrinkage were investigated. It was demonstrated that various types of barrier ribs could be produced successfully by sintering the ribs formed by the molding process.
