PROBLEM TO BE SOLVED: To drive this level shift circuit with single voltage by providing a 2nd P type MOS transistor whose drain is connected to the drain of a 2nd N type MOS transistor, etc., and outputting a signal from the drain of a 1st P type MOS transistor to the next stage circuit. SOLUTION: The source of a P type MOS transistor 11 is connected to a power supply line VDD (13 V) on a high potential side, the source of an N type MOS transistor 12 is connected to a power supply line GND (0 V) on a low potential side, and the drains of the transistors 11 and 12 are connected to each other. Also, the source of an N type MOS transistor 13 is connected to a power supply line VDD(13 V) on a high potential side, the source of a P type MOS transistor 14 is connected to a power supply line GND (0 V) on a low potential side, and the drains of the transistors 13 and 14 are connected to each other. Then, this level shift circuit can be driven by single voltage because a signal is outputted from the drain of the transistor 11 to the next stage circuit.
