Abstract
A method of formimg barrier ribs for a plasma display panel including the steps of: roughening a barrier rib formation surface of a substrate; forming a barrier rib material layer on the roughened barrier rib formation surface; and forming, on the barrier rib material layer, a mask having a pattern corresponding to the barrier ribs to be formed. In addition, forming the ribs includes partially removing the barrier rib material layer by blasting an abrasive against the barrier rib material layer to form the barrier ribs below the mask. Removing the mask reveals barrier ribs for partitioning a discharge space formed on the substrate.
