An LCD(Liquid Crystal Display) is provided to output a control signal, capable of converting dot inversion driving, to a source driver if a voltage ripple applied to common voltage exceeds a predetermined level, and perform inversion into dot inversion driving where crosstalk is not generated, thereby improving display image quality and competitive power of goods. An LCD(Liquid Crystal Display) comprises an LC panel(50) where common lines are formed, an inversion control circuit unit(60) and a source driver(70). The inversion control circuit unit, which includes a common voltage input terminal, a switching transistor, and first and second RC parallel circuits, receives common voltage from the common line, and generates and outputs a driving conversion signal for controlling inversion driving of the LC panel. The source driver receives the driving conversion signal from the inversion control circuit unit, and converts an inversion driving mode.
