A system for compensating for a kickback voltage for a common electrode of a LCD device having a gate line where the gate signal is applied from a first end to a second. The system includes a mechanism configured to apply a constant current to the common electrode at a location corresponding to the first end of the gate line, and mechanism configured to apply a common voltage to the common electrode at a location corresponding to the second end of the gate line. The constant current applied to the common electrode helps to maintain the difference of the common voltages between the positions corresponding to first and second ends of the gate line.
