Abstract
An electrical wiring structure is provided which can be formed simultaneously when non-linear elements containing corrosion resistant metal wires and non-corrosion resistant metal wires are formed. In addition, a manufacturing method of the electrical wiring structure, an electro-optical device substrate provided with the electrical wiring structure, an electro-optical device, and a manufacturing method thereof are also provided. In particular, an oxide layer and the non-corrosion resistant metal wire are sequentially formed on a surface of the corrosion resistant metal wire. An exposed portion of the corrosion resistant metal wire is formed by removing part of the oxide layer. An electrical connection auxiliary member, such as a through-hole formed at the exposed portion or a conductive inorganic oxide film formed on the corrosion resistant metal wire and the exposed portion, is formed to electrically connect the corrosion resistant metal wire and the non-corrosion resistant metal wire.
