摘要： A predrive circuit, a drive circuit and a display device which are capable of driving output elements so as to transmit control signals stably even when reference potentials generated on the output elements side turn to high voltage. A first level shift circuit outputs a flow signal which is an input signal according to a first level shift potential. A second level shift circuit outputs a flow signal which is the flow signal output from the first level shift circuit, according to a second reference potential. A level shift power supply circuit supplies the level shift potential based on a prescribed power supply voltage and the second reference potential to the first level shift circuit and the second level shift circuit.
