Claim 17:
18. The output circuit according to claim 1,
wherein the positive voltage signal has a voltage value that is higher than the reference power supply voltage and less than a predetermined positive power supply voltage, and the negative voltage signal has a voltage value that is lower than the reference power supply voltage and higher than a predetermined negative power supply voltage, and
wherein the second voltage control circuit receives the reference power supply voltage and a positive-polarity side low power supply voltage having a voltage value that is higher than the reference power supply voltage and lower than the positive power supply voltage, and selects and supplies one of the reference power supply voltage and the positive-polarity side low power supply voltage based on the voltage value of the negative voltage signal to the gate of the first NMOS transistor switch.
