Abstract
A display device includes a metal layer composed of multiple layers including a lowermost layer lower in an ionization tendency than a middle layer, the lowermost layer being in contact with and on the oxide semiconductor layer. Each channel region is interposed between a corresponding one of the first electrodes and a corresponding one of the second electrodes, constituting a corresponding one of the thin film transistors. The oxide semiconductor layer is continuous between a pair of channel regions included in an adjacent pair of thin film transistors. The metal layer is continuous between a pair of first electrodes included in the adjacent pair of thin film transistors.
