Abstract
An AC plasma display panel with a coated thin film dielectric layer on the electrodes has a structure which includes double layers of chromium (Cr) and copper (Cu). After three metal layers of chromium, copper, and chromium are formed on a glass substrate, these three metal layers are subjected to patterning with the desired electrode pattern in such a fashion as to eliminate the upper chromium layer. Then, a thin dielectric film of alumina (Al.sub.2 O.sub.3) is evaporated onto the two remaining metal layers forming the electrodes. This combination of two layer metal electrodes and dielectric layer is very useful in providing a self-shifting plasma display panel having high quality and reliability.
