A level shifter circuit with a wide operating voltage range includes an inverter, a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor and a sixth transistor, wherein electrical characteristics of the third transistor and the sixth transistor are opposite to those of the first transistor, the second transistor, the fourth transistor and the fifth transistor, and the second transistor and the fifth transistor have low threshold voltages and high breakdown voltage terminal. The input terminal of the inverter receives the input signal and is electrically coupled to the gates of the fourth transistor and the fifth transistor, while the output terminal thereof is electrically coupled to the gates of the first transistor and the second transistor.
