A method of forming barrier ribs of a plasma display panel includes providing a barrier rib layer (200a,220a) on a substrate and selectively removing portions of the barrier rib layer to form a barrier rib structure (130b 1 ,130b 2 ) defining a plurality of first and second discharge cells (180a,180b,180c), at least one barrier rib (130b 1 ) of the barrier rib structure having a horizontal cross-section that is asymmetric along a center axis thereof, the first (180a) and second (180b) discharge cells having different internal surface areas. |
