A liquid crystal display (LCD) device is provided which includes an LCD panel having first and second substrates facing each other, a plurality of gate and data lines crossing each other to define a plurality of pixel regions; a common electrode; a coupling line perpendicular to the data lines, to generate a signal by a coupling phenomenon with the data lines; and a common voltage generation circuit and a common voltage compensation circuit receiving the signal from the coupling line for compensating the common voltage. The compensated common voltage is applied to the common electrode.
