ABSTRACT:
A surface discharge type plasma display panel has a dielectric layer facing to a discharge gas space and a pair of sustaining electrodes embedded in the dielectric layer and disposed apart from each other by a discharge gap on one of the substrates spaced parallel to each other at the discharge gas space. The dielectric layer includes a pair of first thickness portions formed on far ends of the electrodes from the discharge gap respectively which are larger than a second thickness portion on facing near ends of the facing electrodes. The dielectric layer is provided with a depth from its surface to the substrate larger than that on the second thickness portion between adjacent the electrodes. This plasma display panel prevents any useless expansion of the surface discharge over the sustaining electrodes. The discharge current is reduced and the electrical load on the deriving circuit for the surface discharge PDP decreases to save a power consumption and further the emission efficiency of the surface discharge type PDP is improved.
