Abstract:
A method of fabricating a front plate for a plasma display panel, comprising the steps of:(a) forming a light-shielding structure on a substrate by a mesh printing process or a photolithography process, said light-shielding structure including a black stripe and a transparent electrode gap stopper;(b) forming a transparent conductive layer overlying the upper surfaces of said light-shielding structure and said substrate;(c) coating a first photoresist layer overlying said transparent conductive layer;(d) performing a backside exposure and developing process to the first photoresist layer by using said light-shielding structure as a mask to form a first photoresist pattern, wherein said first photoresist pattern reveals a portion of said transparent conductive layer stacked over said light-shielding structure;(e) removing said portion of said transparent conductive layer stacked over said light-shielding structure;(f) removing the first photoresist pattern, thereby leaving a plurality of transparent electrodes formed on said substrate, and said plurality of transparent electrodes are separated by said black stripe or said transparent electrode gap stopper;(g) forming a metal layer overlying said transparent electrodes and said light-shielding structure;(h) coating a second photoresist layer on said metal layer;(i) forming a second photoresist pattern by performing another photolithography process to the second photoresist layer using a second photomask;(j) etching said metal layer not covered by the second photoresist pattern to form a metal electrode on the corresponding transparent electrode; and(k) removing the second photoresist pattern.
