ABSTRACT:
A method is disclosed for forming an electrode pattern which is free of erosion, separation of a wiring pattern from a substrate, etc., through the use of a lift-up method, which comprises the steps of: etching a transparent, electrically conductive film deposited on a major surface of the substrate for the formation of the transparent electrode pattern; overlaying the whole of the major surface of the substrate with a layer of photoresist; removing a portion of said photoresist layer in the metal electrode pattern; coating substantially the entire major surface of the substrate with a layer of metal electrode material; and removing the remaining photoresist layer with the aid of a resist remover thereby forming the metal electrode pattern.
