ABSTRACT:
A plasma display panel (PDP) capable of reducing the defect rate of a dielectric layer is provided. The PDP includes a first substrate, a second substrate spaced from the first substrate by a predetermined distance, a barrier rib structure disposed between the first and second substrates and defining discharge cells in cooperation with the first and second substrates, sustain electrodes arranged between the first and second substrates, a first dielectric layer covering the sustain electrodes, a phosphor layer arranged within the discharge cells, a frit disposed on edges of the first and second substrates between the first and second substrates, and a discharge gas arranged within the discharge cells, wherein at least portions of corners of the first dielectric layer are curved toward the center of the first dielectric layer so as not to contact the frit.
