A level conversion circuit includes a controlling section supplied with a first power supply voltage and a second power supply voltage different from each other, the controlling section outputting a bias voltage, detecting rising of the first power supply voltage and the second power supply voltage, and outputting a control signal corresponding to a period from the rising of a power supply voltage to stabilization of the power supply voltage, and a level converting section supplied with the control signal and the bias voltage, operation of the level converting section being set in one of a shutdown state and a normal operation state according to the control signal, and the level converting section converting level of an input signal and outputting a signal different in level from the input signal when the operation of the level converting section is set in the normal operation state.
