Abstract
The present invention provides a plasma display panel (PDP) with a structure that can reduce an outer reflection of an external light source and increase the reflection of visible rays emitted from the phosphor, remarkably increase the aperture ratio of the front panel, and remarkably reduce occurrence of a permanent residual image. The PDP includes: a transparent front panel; a rear panel disposed in parallel with the front panel; a plurality of opaque upper barrier ribs disposed between the front panel and the rear panel to define a plurality of discharge cells, and formed of a dielectric material; a lower discharge electrode and an upper discharge electrode disposed within the plurality of opaque upper barrier ribs so as to enclose the discharge cells; a plurality of lower barrier ribs disposed between the plurality of opaque upper barrier ribs and the rear panel; a phosphor layer disposed within a space defined by the plurality of lower barrier ribs; and a discharge gas disposed inside the discharge cells.
