Title: Master for barrier rib transfer mold, and method for forming barrier ribsof plasma display panel using the same

Abstract: The invention relates to a method for forming barrier ribs of a plasmadisplay panel. A master of barrier ribs for fabricating a mold fortransferring barrier ribs is easily produced without the use of amachining technique. In the method for forming barrier ribs of a plasmadisplay panel, a light-transmissive substrate having a predeterminedpattern of a light-tight material formed on a surface and a photosensitivematerial layer bonded on the pattern is exposed to light from the rearsurface of the light-transmissive substrate and developed so as tofabricate a master in which convex portions in a rib configuration areformed on the light-transmissive substrate. By using the master, atransfer mold for barrier ribs is fabricated. A rib material is filled inconcave portions of the transfer mold and transferred onto a substrate fora PDP, thereby forming barrier ribs on the substrate for the PDP.
