MANUFACTURE OF LIQUID CRYSTAL DISPLAY ELEMENT

PURPOSE:To simplify the process forming the insulating film of a metallic wiring part formed on a substrate by forming each corresponding metallic wiring part and terminal part of a wiring pattern and connecting the metallic wiring part to the terminal part after the former is anodized. CONSTITUTION:Plural substrates of liquid crystal display elements are taken out of a large-scaled substrate 5, on which four same wiring patterns 7 composed of plural metallic wiring parts 6... and terminal parts 6a... are formed. The metallic wiring part 6 and the terminal part 6a and formed such that the terminal part 6a is separated from the metallic wiring part 6 and they can be nonconductive. All the metallic wiring parts 6 of four wiring patterns 7 are connected at end part opposite to the direction of the terminal part 6a, and taken out at a point X on one side of the large-scaled substrate 5. The wiring patterns 7... formed on said substrate 5 are anodized in an electrolytic bath with the point X as an anode. At this time, since the terminal parts 6... are not conducted, only the metallic wiring parts 6... form an insulating film.
