Abstract

A composition for barrier ribs of plasma display panels and to a method of fabricating such barrier ribs using the composition is disclosed. The composition for the barrier ribs is SiO.sub.2 --ZnO--PbO--B.sub.2 O.sub.3 based glass. The SiO.sub.2 --ZnO--PbO--B.sub.2 O.sub.3 based glass consists of 10.about.20 wt % of SiO.sub.2, 10.about.30 wt % of ZnO, 5.about.30 wt % of PbO, 10.about.30 wt % of B.sub.2 O.sub.3, 2.about.10 wt % of K.sub.2 O, 0.about.5 wt % of Li.sub.2 O, 1.about.5 wt % of CaO, 3.about.8 wt % of Na.sub.2 O, 1.about.5 wt % of Al.sub.2 O.sub.3, and 0.about.2 wt % of Sb.sub.2 O.sub.3. In the method of forming the barrier ribs, the SiO.sub.2 --ZnO--PbO--B.sub.2 O.sub.3 based glass powder free from an oxide filler is primarily prepared. Paste or slurry is formed by mixing the SiO.sub.2 --ZnO--PbO--B.sub.2 O.sub.3 based glass with an organic vehicle. A thick film, having a predetermined thickness, is formed on the top surface of a lower substrate using the paste or slurry. Desired barrier ribs are, thereafter, formed by processing the paste or slurry film. In the barrier rib formation step, a pattern is formed on the top surface of the paste or slurry film before the paste or slurry film is etched or abraded using the pattern as a mask. The barrier ribs may be formed by stamping the paste or slurry film using a mold having a shape opposed to the desired pattern of the barrier ribs. The barrier ribs may be also formed by patterning a photoresist paste or slurry film.
