Abstract
The present invention is a method for forming ribs for a plasma display panel. The method includes: forming a rib material layer having a predetermined thickness; forming band-shaped barrier rib masks on the rib material layer, each of the barrier rib masks having a pattern corresponding to a barrier rib; forming at least one dummy rib mask for forming at least one dummy rib for each barrier rib, the dummy rib mask being spaced apart from an end of each barrier rib mask in a longitudinal direction of the barrier rib mask; and performing sandblast by blowing abrasive onto the rib material layer and the barrier rib and dummy rib masks, thereby forming the barrier ribs.
