An aluminum alloy film constituting a source / drain wiring and a transparent electrode are directly connected, and both the characteristics of the source / drain wiring and the gate wiring are good and manufactured by a greatly simplified process. A thin film transistor substrate that can be used, and a display device including the thin film transistor substrate are provided. A thin film transistor substrate having a gate wiring and a source wiring and a drain wiring arranged orthogonal to the gate wiring, the composition of a single-layer aluminum alloy film constituting the gate wiring, and the source wiring and the drain wiring. A thin film transistor substrate having the same composition of a single layer aluminum alloy film and a display device including the same. [Selection] Figure 11 |
