  • Patent number: 7371972
    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.

  • Patent number: 6989879
    Abstract: In a liquid crystal panel 1 provided with first and second substrates 1 and 3 bonded by a sealant 3, alignment layers 13 and 23 for covering electrodes 6A and 7A, respectively, are formed up to the regions overlapping the regions for forming up to 3. Accordingly, since there is no space between the alignment 13 or 23 and the sealant 3, a low twist domain does not occur in a liquid crystal 40. Therefore, the vicinity of the inner periphery of the sealant can also be effectively used as the region for displaying images.
