An exemplary liquid crystal display device includes a data line, a pixel, a first gate line, a second gate line, an additional electrode and an additional gate line. The pixel includes a first sub-pixel and a second sub-pixel. The first gate line is electrically coupled to the first sub-pixel. The second gate line is electrically coupled to the second sub-pixel. The first sub-pixel is electrically coupled to the data line to receive a signal provided from the data line. The second sub-pixel is electrically coupled to the first sub-pixel through the additional electrode and to receive a signal provided from the data line through the first sub-pixel. The additional gate line is arranged crossing over the additional electrode and whereby a compensation capacitance is formed between the additional gate line and the additional electrode.
