Abstract
A driving circuit including a shift register is presented, as well as a display device incorporating the driving circuit. The shift register has multiple stages, at least of which includes a first output circuit that generates an output signal O(i) according to a potential at Node Q; a second output circuit that generates a carry signal Cr(i) according to the potential at the Node Q; a controller circuit that controls the potential at the Node Q and the output signal O(i); a first holding circuit that maintains the output signal and the carry signal at low voltage states in response to a Node A reaching a predetermined potential; and a second holding circuit that controls a potential at the Node A, the second holding circuit including a first transistor that lowers the potential at the Node A in response to the carry signal Cr(i).
