PROBLEM TO BE SOLVED: To provide a manufacturing method of barrier ribs of a plasma-display panel, that can effectively level the upper surface of the barrier ribs that divide discharge cells, and can prevent cross-talk phenomenon arising between the discharge cells and the barrier ribs dividing the discharge cells. SOLUTION: This manufacturing method of barrier ribs of a plasma display panel comprises a step (step A) of forming barrier ribs 130 of a prescribed thickness on a substrate 110 provided with an electrode 113, a step (step B) of heating the barrier ribs 130 to the highest sintering temperature T1, a step (step C) of cooling the barrier ribs 130 to an intermediate temperature T2 lower than the highest sintering temperature T1, a step (step D) of pressurizing the upper part of the barrier ribs 130 with a leveling roller 200 to level the upper part of the barrier ribs 130, and a stage (stage E) of cooling the barrier ribs 130 to the normal temperature. |
