Abstract: A disclosed display device includes a first oxide semiconductor layer and an oxide semiconductor connection wire both formed from an oxide semiconductor material layer over a substrate. The oxide semiconductor connection wire is integrally connected to the first oxide semiconductor layer and has a lower sheet resistance than the first oxide semiconductor layer. The display device also includes a first gate electrode either over the first oxide semiconductor layer or between the first oxide semiconductor layer and the substrate. The display device further includes a first gate insulation layer between the first oxide semiconductor layer and the first gate electrode.

Abstract: A shift register of the present disclosure includes a plurality of stages. Each stage includes transistors belonging to a first group for activating a Q node, transistors belonging to a second group for discharging odd and even QB nodes, transistors belonging to a third group for being activated by the odd and even QB nodes and for discharging the Q node, and a sensing circuit for sensing a threshold voltage of at least one of the transistor belonging to the third group at a period when the Q node is discharged. The shift register of the present disclosure avoids the problem of erroneous operation due to lowering of device characteristics.
