1. A shift circuit of a shift register including a plurality of shift circuits that are cascade-connected, the shift circuit comprising:

  • an input circuit which includes an input terminal to which an output signal of a shift circuit in a previous stage is supplied as an input signal, a reset terminal to which an output signal of a shift circuit in a next stage is supplied as a reset signal, and a first node, and is configured to set a potential of the first node as a potential of the input signal, as the input signal is input;

    an inverting circuit including a second node and a reference voltage terminal, wherein the second node is configured to have a potential that is reverse to the potential of the first node obtained by reversing the potential of the first node;

    an output circuit which includes a first clock terminal to which a first clock signal is supplied, and an output terminal which outputs the output signal, and is configured to output a potential of the output signal as a potential according to the first clock signal to the output terminal depending on the potential of the first node and the potential of the second node; and

    a hold circuit configured to maintain the potential of the second node as a high level potential when the potential of the first node is not the potential of the input signal.
