Abstract
A stage circuit including a plurality of stages connected to each other, where each of the stages includes: an output unit configured to output a voltage of a first power source or a signal of a third input terminal to an output terminal, based on a voltage applied to a first node or a second node; a first driver configured to control a voltage at a third node, based on signals of a first input terminal, a second input terminal and the third input terminal; a second driver configured to control the voltage at the first node, based on the signal of the second input terminal and the voltage at the third node; and a first transistor connected between the second node and the third node and maintained in a turn-on state.
