A back plate structure of the plasma display panel is provided. The horizontal barrier ribs and the vertical barrier ribs are crossed over to form the I at t i c e - Ii k e discharge cells. The horizontal barrier ribs or the vertical barr i e r r i b s have t h e projections p rot rude d to t h e discharge cells, which can make the air exhaust from the sides of the projections during the printing of the phosphor paste. The nonuniform-thickness phenomenon caused by the bubbles in the phosphor material printed on the bottom-surface of the discharge cell is improved, and so flicker-noises on the display panel are eliminated. Furthermore, the discharge space is increased owing to the increased packing-density of the phosphor material. Therefore, the illumination efficiency of the PDP is promoted. Besides, the horizontal barrier rib and the vertical barrier rib may also be designed to have a height difference to improve the exhausting efficiency during the printing process of the phosphor paste.
