Abstract
A shift register circuit comprises a shift register, and a signal output circuit including J number of scan signal output circuits (J is an integer of 2 or more) operating by being connected with the shift register to respectively output J number of scan signals. The J number of scan signal output circuits share a first QB node and a second QB node of the shift register, a common output terminal of the shift register, and a first voltage line, operate based on a potential of the first QB node, a potential of the second QB node, a common output signal output through the common output terminal, a first voltage transferred through the first voltage line, and an Ith clock signal transferred through an Ith clock signal line, and output the J number of scan signals through output terminals which are respectively divided.
