A plasma display panel with an improved barrier rib design. The barrier ribs between the substrates are designed to have differing heights to compensate for the difference in the amount of phosphor layer material formed on the tops of the barrier ribs. By designing the barrier ribs so, gaps between the tops of the barrier ribs and the front substrate are reduced or eliminated thus improving image quality. At the same time, the deposition of the phosphor layers is made easier by jet nozzle ejection so that the novel plasma display panel is easy to make. Fluorescent phosphor layers are applied in neighboring discharge cells with the first barrier members interposed there between. A total height of the first barrier members and the phosphor layers applied thereon is substantially the same as the height of the second barrier ribs members. This may protect the plasma display panel from cross-talk phenomenon.
