Patent abstract
The present invention relates to a plasma display panel. The plasma display panel includes black matrices formed in a front substrate, and first barrier ribs, which are formed opposite to the black matrices on a rear substrate and partition pixel cells. The first barrier ribs have a width wider than that of the black matrices. Even if misalignment occurs during a process of adhering substrates, the black matrices do not protrude into discharge spaces. Therefore, the defective ratio can be lowered and the picture quality can be improved.
