Abstract:
A method of forming barrier ribs for a plasma display panel having a plurality of discharge cells intervening between a pair of glass substrates formed with electrodes, the discharge cells being partitioned by the barrier ribs, said method comprising the steps of:(a) forming an uncured barrier rib material layer having flexibility on the surface of at least one of said glass substrates, on which said electrodes are formed; (b) exposing the barrier rib material layer to a vapor atmosphere of a solvent of the barrier rib material for a predetermined period of time so as to adjust the hardness of the barrier rib material; (c) rolling a roller, which has an intaglio recessed pattern corresponding to a desired pattern for the barrier ribs, on said barrier rib material layer so that the recessed pattern contacts and embosses the barrier rib material layer to form freestanding structures corresponding to the recessed pattern; and (d) drying and firing a barrier rib material shaped into the freestanding structures, whereby the barrier ribs for partitioning discharge cells are formed on the glass substrate.
