PURPOSE: A driving circuit of a liquid crystal display is provided to control the minute flickering by independently controlling respective different common voltages applied to respective locations of an LCD panel. CONSTITUTION: A current applied through a resistor(R1) is reduced by a resistor(R2) and a variable resistor(VR1) to be charged into a capacitor(C1) in the common voltage generator(100). The voltage of the charged capacitor(C1) becomes a common voltage(Vcom1). Second and third common voltage generators(200, 300) control the charging amounts of capacitors(C2, C3) according to the control of variable resistors(VR2, VR3) to have different voltage of the capacitors(C2, C3). The common voltages(Vcom2, Vcom3) are independently changed according to the variations of the variable resistors(VR2, VR3).
