1. A level shifter circuit comprising:

  • a first voltage conversion circuit for generating a drive voltage that is lower than a first power supply voltage supplied from the first power supply line and is in correspondence with the first power supply voltage, and generating and outputting complementary signals corresponding to an input signal using the drive voltage;

    a second voltage conversion circuit for generating and outputting a signal corresponding to voltages of the complementary signals output from the first voltage conversion circuit using a second power supply voltage supplied from a second power supply line; and

    an output latch circuit for performing holding in accordance with the voltage of the signal output from the second voltage conversion circuit.
