ABSTRACT:
The present invention relates to a plasma display panel, that is capable of preventing the discoloration of a substrate caused by migration of a metal bus electrode or metal paste's running down.The plasma display panel includes a transparent electrode; a metal bus electrode; a first light shielding layer formed between the transparent electrode and the metal bus electrode on each discharge cell; a second light shielding layer formed between the adjacent discharge cells. The first light shielding layer and the second light shielding layer are different from each other in at least one of a thickness and a pigment concentration.
