PURPOSE: A driving device for LCD module is provided to intercept doubly over-current by arranging serially two capacitors between an input voltage source and a ground voltage source. CONSTITUTION: A driving device for LCD module includes an AC voltage source, a doubling circuit(40), and two or more capacitors. The doubling circuit is used for adding a DC voltage to AC voltage supplied from the AC voltage source. The capacitors are serially connected between the doubling circuit and a ground voltage source. The doubling circuit includes the first diode(3D1) and the second diode(3D2). The first diode is used for supplying DC voltage. The second diode is connected between the first diode and the capacitors. The first capacitor(3C1) is connected among the first diode, the second diode, and the AC voltage source.
