Front panel for plasma display panel and method for producing the same
The present invention provides a front panel for a plasma display panel which can suppress the incidence of chipping of the barrier rib of a rear panel for a PDP, can enhance the stability of initial electron emission in a dielectric layer, and can reduce a voltage required for maintaining a wall charge. The front panel for a plasma display panel includes a substrate, a plurality of electrodes formed on the substrate, a dielectric layer formed to cover the respective electrodes and the substrate, a dielectric-protection layer formed to cover the dielectric layer, and powder components dispersed on the dielectric-protection layer, wherein an annealed layer having a thickness of 10 to 300 nm is formed on at least the exposed surface of each of the powder components, wherein said exposed surface does not contact the dielectric-protection layer.
