A level shift circuit includes a first circuit connected between a first power supply terminal (PST) and an output terminal (OT) of the level shift circuit to set OT to a first voltage (V1) when conducting, a second circuit connected between a second PST and OT to set OT to the second voltage (V2) when conducting, and a third circuit that receives an input signal and a feedback signal from OT so that, when OT=V2 and input=a third voltage (V3), the first circuit conducts, and when OT=V1, the first circuit is made nonconductive irrespective of the value of the input signal. The second circuit is made conductive and nonconductive, when the input=a fourth voltage (V4) and V3, respectively. A high/low relationship of V1, V2=that of V3, V4. The input between V3, V4 has a lower amplitude than the output signal between V1, V2.
