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.

Electrical wiring structure, manufacturing method thereof, electro-optical device substrate having electrical wiring structure, electro-optical device, and manufacturing method thereof

In a liquid crystal panelprovided with first and second substratesandbonded by a sealant, alignment layersandfor covering electrodesA andA, respectively, are formed up to the regions overlapping the regions for forming up to. Accordingly, since there is no space between the alignmentorand the sealant, a low twist domain does not occur in a liquid crystal. Therefore, the vicinity of the inner periphery of the sealant can also be effectively used as the region for displaying images.

Liquid crystal panel and method of fabricating the same

A liquid crystal apparatus is provided with a substrate holding an electro-optical material, and a plurality of wires that have routing wire portions formed in a region of the substrate other than a region opposing the electro-optical material. The routing wire portion of each of the wires has a first portion and a second portion that is narrower than the first portion. In an inspection process of the liquid crystal apparatus having such a configuration, a plurality of inspection terminals for supplying predetermined drive signals to the wires are brought into contact with the second portions of the wires.
