Plasma display panel

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;
• an X electrode and a Y electrode fixed to the transparent front substrate;
• a first dielectric layer covering the X electrode and the Y electrode, and having a groove with a first inclined surface interposed between the X electrode and the Y electrode;
• a protecting layer covering the first 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.
