摘要:
An anodized oxide film of Al is formed on a scanning signal line and a gate electrode. An alloy of Al containing Ta and Ti is used as material of each of the scanning signal line and gate electrode. The thickness of the anodized oxide film is set to 1,000 angstroms or more. The fabrication yield and reliability can be improved.
