ABSTRACT:
A plasma display panel includes a plurality of discharge cells formed with a plurality of partition walls arranged at fixed intervals between a front substrate and a rear substrate disposed in parallel spaced at a certain distance. A fluorescent material film is formed on a portion of an inside surface of each of the discharge cells. A discharge gas is sealed in each of the discharge cells and is converted into a plasma upon the occurrence of a discharge in each of the discharge cells. Each of the partition walls is formed with a stack of at least more than one permanent magnets magnetized with N and S poles for forming a magnetic field in the discharge cell. The electrons existing in the plasma are thus accelerated toward the fluorescent material film upon occurrence of a discharge in the discharge cell by the magnetic field such that the fluorescent material film can be excited, whereby a luminance of a panel screen can be improved, equal sized magnetic partition walls can be formed, and production time of the magnetic partition walls can be shortened.
