Patent ID: 7371972

Claim:
A liquid crystal panel comprising: a first substrate; a second substrate opposed to the first substrate and including a mounting section that extends beyond the first substrate; at least one of an IC chip and a flexible cable mounted at the mounting section of the second substrate; a liquid crystal material between the first and second substrates; a seal material that seals the liquid crystal within a sealed area between the first and second substrates; a corrosion resistant metal wire formed from a corrosion resistant metal, said corrosion resistant metal wire formed on one of the first and second substrates and extending from an area disposed outside the sealed area into the sealed area; an oxide layer of the corrosion resistant metal formed on a surface of the corrosion resistant metal wire, at least one through hole extending through the oxide layer and into the corrosion resistant metal wire so that the through hole forms a sidewall of the corrosion resistant metal wire; a non-corrosion resistant metal wire including a first section disposed within the sealed area to the inside of the seal material and a second section, the first section extending from the seal material to the mounting section of the second substrate, the first and second sections extending into the through hole and physically contacting the sidewall of the corrosion resistant metal wire at a location inside the sealed area; and a transparent conductive oxide film covering the second section of the non-corrosion resistant material metal wire and not covering the first section of the non-corrosion resistant material metal wire.
