In order to improve cost and efficacy of AC PDP with metal discharge electrodes, a new II-type metal electrodes are suggested. The suggested asymmetrical II-type metal electrode is improved in the luminance, power and efficacy than the conventional metal electrode by 7.5%, 6%, and 14%, respectively. The efficacy of the suggested asymmetrical II-type metal electrode is almost the same with the conventional ITO electrode. Moreover, the address time of the II-type metal electrode is shorter than the conventional ITO electrode.
