The present invention relates to a plasma display panel and a manufacture method thereof in which a color mixture of emitted light can be prevented and a contrast characteristic can be improved. The plasma display panel includes: a first barrier rib for partitioning a plurality of sub-pixels; and a second barrier rib formed to function as a boundary between one unit pixel constituting of the plurality of sub-pixels and an adjacent unit pixel, and partition the unit pixels, wherein the second barrier rib has a greater width than the first barrier rib. The method includes the steps of: coating a first and second barrier rib paste on a dielectric material formed on a glass; and placing and exposing an irregular pattern mask on the first and second barrier rib paste to form a first barrier rib pattern and a second barrier rib pattern each having a different width.
