Abstract
A plasma display panel and a multi plasma display panel are disclosed. The multi plasma display panel includes a plurality of plasma display panels that are positioned adjacent to one another. Each of the plurality of plasma display panels includes a front substrate, a back substrate positioned opposite the front substrate, and a plurality of barrier ribs positioned between the front substrate and the back substrate. The plurality of barrier ribs partition a plurality of discharge cells. A size of a discharge cell in a boundary portion between two plasma display panels of the plurality of plasma display panels is greater than a size of a discharge cell in other portions.
