Provided is a digital circuit (30) that comprises: a switching circuit (31) having first transistors (32, 33) supplied with power supply potentials (VDD, VSS); correcting circuits (34, 36) connected between an input terminal (IN) inputted with an input signal and control terminals (gates) of the first transistors; capacitors (C2, C3) connected between the control terminals and the input terminal; diode-connected second transistors (35, 37) that are provided between nodes (N5, N6) between the capacitors and the control terminals and the power supply potentials and have the substantially same threshold voltage as the first transistors; and switches (SW2, SW3) connected in series with the second transistors.
