1. A display device comprising:

  • a plurality of pixels; and

    a driving circuit for driving the plurality of pixels;

    wherein;

    the driving circuit includes a single channel bidirectional shift register adapted for bidirectional scanning in a first direction and a second direction;

    the single channel bidirectional shift register includes an RS flip-flop circuit;

    the RS flip-flop circuit includes a first transistor having a first electrode connected to an output terminal and having a second electrode to which a second scanning direction control signal is applied, and a second transistor having a first electrode connected to an output terminal and having a second electrode to which a first scanning direction control signal is applied;

    a resetting signal is applied to a control electrode of the first transistor in a first scanning direction, and a setting signal is applied to the control electrode of the first transistor in a second scanning direction which is a reverse direction to the first scanning direction; and

    the setting signal is also applied to a control electrode of the second transistor in the first scanning direction, and the resetting signal is also applied to the control electrode of the second transistor in the second scanning direction.
