A Plasma Display Panel (PDP) includes a first panel and a second panel, the first panel facing the second panel and having a plurality of discharge cells arranged between the first panel and the second panel. The first panel includes a first substrate, X and Y electrodes extending on the first substrate, and a first dielectric layer adapted to cover the X and Y electrodes and having groove shaped field concentration units arranged on a surface thereof facing the discharge cells. An inner surface of each field concentration unit is concave with respect to a central portion thereof. |
