Abstract

Each of a plurality of stages of a driving circuit includes an input circuit (131) configured to transmit a start signal (STV) to a first node (A), a first output circuit (135a) connected to a first terminal (V1) to which a first voltage (VGH) is input and a second terminal (V2) to which a second voltage is input (VGL), the first output circuit being configured to output an output signal (GOUT) to a signal line, a second output circuit (137a) connected to the first terminal and a third terminal (V3) to which a third voltage (VGL2) is input, the second output circuit being configured to output a carry signal (COUT) to a next stage, and a control circuit (133a) configured to control voltages of nodes (QB, Q) to which the first output circuit and the second output circuit are connected according to a voltage of the first node.
