Abstract: Disclosed are an LCD device and a driving method thereof, which save the manufacturing cost that is expended by the application of four-color (RGBW) sub-pixels, and enhance an aperture ratio and brightness, thus increasing display quality. The LCD device includes an upper substrate, a lower substrate, and a liquid crystal layer. A plurality of R, G, B and W color filters are formed at the upper substrate. In the lower substrate, a plurality of R, G, B and W sub-pixels are formed in respective regions defined by intersection of a plurality of gate lines and data lines. The liquid crystal layer is formed between the upper substrate and the lower substrate. Each of the pixels is configure with three-color sub-pixels of the R, G, B and W sub-pixels. Pixels of the plurality of pixels including a W sub-pixel share a one-color sub-pixel included in a pixel adjacent thereto, and display a color image.
