Abstract
A level shift circuit includes an initial stage circuit section which converts an input signal into a signal having a voltage level of the first high voltage power supply as a high level and a voltage level of the first low voltage power supply as a low level, an intermediate stage circuit section which level-shifts the signal output from the initial stage circuit section into a signal having the voltage level of the first high voltage power supply as a high level and the voltage level of the second low voltage power supply as a low level, and a final stage circuit section which level shifts the signal output from the intermediate stage circuit section into a signal having the voltage level of the second high voltage power supply as a high level and the voltage level of the second low voltage power supply as a low level.
