A level shift circuit includes an input port to which an input signal is input, a first signal amplifying unit configured to amplify the input signal input to the input port, a node at the first signal amplifying unit to output the amplified signal, a level shift input port to which a level shift voltage for controlling a DC level of the node is input, a first supply voltage configured to drive the first signal amplifying unit, and a level shift voltage generation circuit configured to generate the first supply voltage and the level shift voltage.
