ABSTRACT:
A liquid crystal apparatus includes a liquid crystal panel side electrode extending from a liquid crystal panel and an external circuit side electrode extending from an external circuit and connected to the liquid crystal panel side electrode for driving the liquid crystal panel, by using conductive material. The liquid crystal panel side electrode includes a laminated film made of an indium tin oxide film having a surface and a metal film on the surface. The metal film is selected from one of a molybdenum film and an aluminum film. The liquid crystal panel side electrode has a left portion of the metal film and an indium tin oxide film opening area, at a connection area between the liquid crystal panel side electrode and the external circuit side electrode. The indium tin oxide film of the liquid crystal panel side electrode is covered with the metal film over the entire surface thereof. The liquid crystal panel side electrode is formed in a stripe shape, and the left portion of the metal film of the liquid crystal panel side electrode at the connection area is formed to have a width 1/30 to 1/3 times as narrow as a width of the stripe.
