Abstract

The disclosure includes: first level shift part generating a voltage signal by converting an input voltage signal into amplitude between first negative and positive polarity power supply voltages; second level shift part generating a first polarity voltage signal by converting the voltage signal into amplitude between a reference and the first positive polarity power supply voltage; third level shift part outputting a first-polarity high voltage signal by converting the first polarity voltage signal into amplitude between a higher second positive polarity power supply voltage and the reference; fourth level shift part generating a second polarity voltage signal by converting the voltage signal into amplitude between the reference and the first negative polarity power supply voltage; and fifth level shift part outputting a second-polarity high voltage signal by converting the second polarity voltage signal into amplitude between a lower second negative polarity power supply voltage and the reference.
