Patent ID: 7538493

Claim:
A plasma display panel, comprising: a transparent front substrate and a rear substrate facing each other; partition walls that define discharge cells and which are interposed between the transparent front substrate and the rear substrate; a first electrode and a second electrode interposed between the transparent front substrate and the rear substrate and corresponding to the discharge cells; a dielectric layer covering the first electrode and the second electrode and having a groove with a first inclined surface interposed between a first electrode and a second electrode; a protecting layer covering the dielectric layer; a fluorescent layer disposed in a discharge cell; and a discharge gas disposed in the discharge cell, wherein a (1,1,1) growth direction of crystals of the protecting layer corresponding to the first inclined surface of the groove is substantially perpendicular to the first inclined surface of the groove, wherein the dielectric layer has a second inclined surface of the groove interposed between the first electrode and the second electrode and a recessed surface coupled between the first inclined surface and the second inclined surface, and wherein a portion of the protecting layer corresponding to the first inclined surface or the second inclined surface is thicker than a portion of the protecting layer corresponding to the recessed surface.
