Method of manufacturing barrier ribs for a plasma display panel

A method for forming plasma display panel structure comprising:

• forming a plurality of address electrodes on a back substrate, wherein said address electrodes are arranged in parallel to each other;
• forming a dielectric layer over said address electrodes and said back substrate;
• forming a barrier rib structure over said dielectric layer, wherein said barrier rib structure comprises:
• a plurality of barrier ribs arranged in the first direction and parallel to each other, wherein each of said barrier ribs is formed by a plurality of wide sections and narrow sections, and said wide sections and said narrow sections are alternately formed in the first direction, and said barrier ribs comprises a first barrier rib, a second barrier rib and a third barrier rib;
• and
• a plurality of barrier ribs with a fin-sharp barrier ribs extended from said barrier ribs arranged in a second direction and parallel to each other and located between said barrier ribs arranged in a first direction, wherein said barrier ribs arranged in a second direction are respectively connected with corresponding said wide sections to form a plurality of discharge spaces;
• performing a sintering process to form a height difference said wide sections and said narrow sections;
• and
• covering a front substrate over said barrier rib structure.
