ABSTRACT:
The present invention relates to a plasma display panel, and more particularly, to a plasma display panel and fabricating method thereof, by which brightness thereof is enhanced. According to an embodiment of the present invention, a plasma display panel includes a front substrate, a rear substrate confronting the front substrate, a pair of sustain electrodes formed parallel to each other on a confronting surface of the front substrate, a dielectric layer covering the confronting surface of the front substrate and a pair of the sustain electrodes, anda protective layer coated on the dielectric layer, wherein if the dielectric layer and the protective layer configure a functional layer, at least one or more trenches are formed in the functional layer. By the present invention, a discharge space having a high electric field concentrated thereon on discharge expands to increase ultraviolet ray density intensity, whereby more phosphor can be excited to raise brightness. And, if the discharge space expands, it is able to acquire a brightness level equal to that of the related art with a discharge initiation voltage at a level lower than that of the related art.
