Abstract
A shift register is implemented that can increase the reliability of long-term operation regarding the driving of gate bus lines over a conventional configuration. The shift register is allowed to operate by clock signals of eight or more phases with an on-duty of less than ½. A stabilization node control portion brings a stabilization node (NB) to an on level for a period less than 50 percent of a normal operation period, based on two or more clock signals among the clock signals of eight or more phases, the stabilization node (NB) being connected to a gate terminal of a thin film transistor that contributes to the drawing of a potential of an output control node (NA) to a VSS potential.
