SHIFT REGISTER AND DISPLAY DEVICE PROVIDED THEREWITH

摘要

This invention implements a shift register, for driving a scanning-signal line, that makes it possible to reduce the bezel width and power consumption of a display device while ensuring reliability over long-term operation. In each of a number of stages, an output-control-node stabilization section (420) of a circuit constituting that stage comprises the following: a thin-film transistor (M5) wherein a fourth clock (CKD) that changes from an OFF level to an ON level when a scanning signal outputted by the previous stage is to change from an OFF level to an ON level is supplied to the gate terminal, the drain terminal is connected to an output-control node (NA), and the scanning signal outputted by the previous stage is supplied to the source terminal; and a thin-film transistor (M6) wherein a third clock (CKC) that changes from an OFF level to an ON level when a scanning signal outputted by the next stage is to change from an OFF level to an ON level is supplied to the gate terminal, the drain terminal is connected to the aforementioned output-control node (NA), and the scanning signal outputted by the next stage is supplied to the source terminal.
