Abstract:
1. A plasma display panel, comprising: a front panel; a rear panel disposed parallel to the front panel; first barrier ribs formed of a dielectric material and disposed between the front panel and the rear panel so as to define a plurality of discharge cells; front discharge electrodes disposed inside the first barrier ribs so as to surround the discharge cells, and spaced from side surfaces of the discharge cells toward interiors of the first barrier ribs by an electrode-burying depth; rear discharge electrodes disposed inside the first barrier ribs so as to surround the discharge cells, and spaced from the side surfaces of the discharge cells toward the interiors of the first barrier ribs by the electrode-burying depth at a rear side of the first discharge electrodes; a plurality of phosphor layers disposed inside the discharge cells for receiving ultraviolet rays and emitting visible rays, said phosphor layers having different dielectric constants; and a discharge gas deposited in the discharge cells; wherein an electrode-burying depth corresponding to discharge cells in which phosphor layers having a lowest dielectric constant are disposed is smaller than an electrode-burying depth corresponding to discharge cells in which phosphor layers having a relatively high dielectric constant are disposed.
