ABSTRACT:
A Plasma Display Panel (PDP) includes: a front panel having a front plate and a plurality of electrodes arranged on a surface of the front plate in a predetermined pattern and a back panel having a back plate facing the front plate, a plurality of electrodes arranged on a surface of the back plate in a predetermined pattern to correspond to the plurality of electrodes of the front plate, and at least one ventilation hole. At least two back plates are formed by cutting one base plate on which at least two ventilation holes are formed. Each ventilation hole has a first width in a first edge direction of the back plate and a distance from the first edge to a center of the at least one ventilation hole is at least twice that of the first width.
