Plasma display panel (PDP)

Abstract

Provided is a plasma display panel (PDP) having a structure that prevents a frit from penetrating into a display area during a process of sealing the PDP. The PDP includes: a pair of substrates spaced apart from each other and facing each other; a sheet interposed between the pair of substrates and comprising a barrier rib part, defining discharge cells, and a dielectric part disposed on edges of the barrier rib part; first discharge electrodes disposed in the sheet; second discharge electrodes disposed in the sheet and spaced apart from the first discharge electrodes; a frit disposed between the pair of substrates and the dielectric part and sealing the pair of substrates; a groove formed on at least one of the pair of substrates and where at least a part of the frit is disposed; phosphor layers arranged in the discharge cells; and a discharge gas sealed in the discharge cells.
