Abstract

The invention provides a method for forming dielectric protection layers of a plasma display panel (PDP). The method comprises the following steps: firstly, forming a front electrode on a front substrate; secondly, forming a front dielectric layer on the front substrate and the front electrode; thirdly, forming a first protection layer on the front dielectric layer; and finally, forming a second protection layer on the first protective layer, wherein the second protection layer is made of diamond particles. The invention also provides a PDP having double dielectric protection layers on the front substrate. The double dielectric protection layers formed by the method can reduce the ignition voltage of the plasmas, reduce the ignition delay and improve the luminous efficiency of the plasmas.
