ABSTRACT:
A plasma display panel having a uniformly distributed firing voltage despite of irregular discharge gaps, the plasma display panel including a first substrate, a second substrate facing the first substrate, barrier ribs between the first and second substrates to define discharge cells, address electrodes corresponding to the discharge cells and extending in a first direction, first and second electrodes respectively extending in a second direction crossing the first direction and formed on any one of the first and second substrates, corresponding to the discharge cells, and a dielectric layer covering the first and second electrodes, where the first and second electrodes are spaced apart from each other to form a discharge gap having distances, the dielectric layer having varied permittivities according to distances of the discharge gaps to improve discharge uniformity according to the distances of the discharge gaps.
