LEVEL SHIFT CIRCUIT, AND DRIVER AND DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a high-speed level shift circuit that prevents an increase in circuit scale. SOLUTION: The level shift circuit includes third circuits M3, M1 and M2 which are connected between a first power supply terminal E1 for supplying first voltage VE1 and a second power supply terminal E2 for supplying second voltage VE2, and makes the first circuit M4 conductive when the input signal IN of the level shift circuit shows a value corresponding to third voltage VE3, and makes the first circuit M4 non-conductive regardless of the value of the input signal IN when an output terminal 4 shows a value corresponding to the first voltage VE1. A second circuit M5 is made conductive when the inverted signal INB of the input signal shows a value corresponding to the third voltage VE3, and is made non-conductive when the inverted signal INB of the input signal shows a value corresponding to fourth voltage VE4, wherein the relation of the first to fourth voltage is VE2≤VE4
