Abstract
A shift register according to the present invention is a shift register in which a plurality of unit circuits are connected in cascade, wherein the unit circuit includes a first output transistor whose current path is connected between an output terminal and a clock terminal to which a first clock signal is provided; a second output transistor whose current path is connected between the output terminal and a predetermined potential node; a setting device which, when a control signal is active, sets a signal level of the output terminal to a predetermined signal level; a first output control device which provides a signal level of the control signal to a control electrode of the first output transistor to turn off the first output transistor when the control signal is active; and a second output control device which turns off the second output transistor when the control signal is active.
