Patent abstract
A thin-film transistor substrate in which an aluminum alloy film composing a source/drain wiring is directly connected with a transparent electrode. The thin-film transistor substrate includes a gate wiring, and source wiring and drain wiring, the gate wiring and the source and drain wiring being arranged orthogonally to each other. The single-layer aluminum alloy film composing the gate wiring and the single-layer aluminum alloy film composing the source wiring and the drain wiring are the same in composition. Furthermore, display devices can be mounted with the above thin-film transistor substrates.
