Claim 16:
17. 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 first voltage control circuit receives the reference power supply voltage and a negative-polarity side low power supply voltage having a voltage value that is lower than the reference power supply voltage and higher than the negative power supply voltage, and selects and supplies one of the reference power supply voltage and the negative-polarity side low power supply voltage based on the voltage value of the positive voltage signal to the gate of the first PMOS transistor switch.
