This invention relates to a liquid crystal display device and its driving method for improving a visual picture quality. A liquid crystal display device according to an embodiment includes a liquid crystal display panel where plural pixels composed of sub-pixels arranged in a fixed pattern are arranged by the unit of one horizontal line; a timing controller for controlling the gray level realization of digital data inputted from a system; and a data drive circuit that differently realigns a data pattern of the digital data by the unit of one horizontal line for each k horizontal period, that converts the digital data of the realigned data pattern into analog data voltages, and that makes the analog data voltages, which are buffered in accord with the realigned data pattern, in accord with an arrangement pattern of the sub-pixels constituting each pixel to supply the analog data voltages to each pixel. |
