Abstract
The present invention relates to a plasma display panel (PDP) that includes a first substrate, an address electrode formed on the first substrate, a dielectric layer formed on the first substrate and covering the address electrode, a barrier rib formed on the dielectric layer, a second substrate, a display electrode formed on the second substrate, a dielectric layer formed on the second substrate and covering the display electrode, and a protection layer formed on the dielectric layer of the second substrate. Discharge cells are defined by barrier ribs, and a phosphor layer is formed in the discharge cells. Barrier ribs contains inorganic adsorbent. When a PDP is operated for a long time, residual carbon or water is generated inside discharge cells, and thereby contaminates a discharge gas contained in the discharge cells. The inorganic adsorbent included in the barrier ribs absorb the residual carbon or water improving efficiency and lifespan of the PDP.
