Abstract:
1. A PDP (plasma display panel), comprising: a front substrate; a rear substrate arranged opposite to the front substrate; a plurality of front barrier ribs arranged between the front substrate and the rear substrate and comprising a dielectric material, the front barrier ribs defining discharge cells together with the front and rear substrates; rear barrier ribs arranged between the front barrier ribs and the rear substrate; front and rear discharge electrodes arranged within the front barrier ribs and surrounding the discharge cells and spaced apart from each other; phosphor layers arranged within the discharge cells, the phosphor layers being arranged on at least a side of the rear barrier ribs; and a discharge gas arranged within the discharge cells, each front discharge electrode includes a loop portion having a predetermined width, a cross section of the loop portion having a regular polygonal shape, the loop portion surrounding one of said discharge cells, a ratio R of a minimum distance to a maximum distance from a symmetry axis of a loop portion of a front discharge electrode to an inner side of the front discharge electrode satisfies the inequality 1.0/√{square root over (2)}≦R≦1.
