Abstract:
Disclosed is a liquid crystal display device comprising a display part. The liquid crystal display device allows a common electrode voltage swinging depending on a gate off voltage of the display part to be fed-back through a feed-back circuit and to be held at a constant level, thus stabilizing the common electrode voltage and the gate off voltage coupled to a capacitance component, thereby preventing a picture displayed on the liquid crystal display panel from being divided into blocks. The common electrode voltage is detected at a position capable of being connected to the common electrode. The detected common electrode voltage is input into a comparator for outputting the common electrode voltage. The output of the comparator is controlled to thereby control the swing of the common electrode voltage.
