Abstract

This invention provides a patterning method for a transparent electrode capable of preventing heat damages and insulation failure or the like even when a ZnO film is used. An ITO film 3 is formed on a transparent substrate 1 by sputtering and the ZnO film 4 is formed on the ITO film 3 by sputtering. Then, regions to be irradiated of the ITO film 3 and the ZnO film 4 are eliminated and patterned by Nd-YAG laser irradiation.
