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.

Abstract translation: 公开了一种LCD装置及其驱动方法，其节省了由四色（RGBW）子像素应用所消耗的制造成本，并且增加了开口率和亮度，从而提高了显示质量。 LCD装置包括上基板，下基板和液晶层。 在上基板上形成多个R，G，B和W滤色器。 在下基板中，在由多条栅极线和数据线的交点限定的各个区域中形成多个R，G，B和W子像素。 液晶层形成在上基板和下基板之间。 每个像素配置有R，G，B和W子像素的三色子像素。 包括W子像素的多个像素的像素共享与其相邻的像素中包括的单色子像素，并且显示彩色图像。
