Abstract
An active matrix liquid crystal display device with a plurality of thin-film transistors each including a gate electrode, preferably made of an aluminum film formed over a glass substrate, and a gate insulator preferably made of an upper silicon nitride film and a lower anodized oxide film of the aluminum film. Dummy gate lines DGL are disposed outside the outermost scanning signal line GL, and dummy data lines DDL are disposed outside the outermost video signal line DL so as to prevent breakage of outermost signal lines.
