Abstract
A liquid crystal display device is disclosed, which may compensate for a common voltage by reflecting all of noises by which a plurality of common electrodes are affected. The liquid crystal display device comprises a liquid crystal display panel including a plurality of data lines, a plurality of gate lines crossing the data lines, and a plurality of pixels provided at crossing regions of the data lines and the gate lines and including pixel electrodes and common electrodes to which a common voltage is supplied, wherein a common electrode of the common electrodes is shared by two or more of the plurality of pixels. The liquid crystal display panel also includes a plurality of feedback lines that overlap the common electrodes, the plurality of feedback lines receiving a variation of the common voltage that is reflected by the common electrodes onto the plurality of feedback lines.
