A level shift circuit includes a high voltage circuit, a clamp circuit, an input circuit, and a bypass circuit. The high voltage circuit is electrically connected to a high voltage terminal. The clamp circuit can prevent the transistors of the high voltage circuit from high voltage stress when a voltage level of the high voltage terminal is greater than a voltage level of a voltage source. The bypass circuit is used to bypass the clamp circuit when a voltage level of the high voltage terminal is smaller than a voltage level of transistor breakdown voltages.
