A rotation driving method of a LCD device includes a first step of rotating the LCD device 180° such that source driving units are disposed at a lower portion of the liquid crystal panel, a second step of outputting scan signals from gate driving units in reverse order, a third step of reestablishing image data provided to the source driving units, a fourth step of reversing arrangement of the image data outputted to sub-pixels, a fifth step of shifting and outputting the image data corresponding to selected odd horizontal lines and even horizontal lines by one sub-pixel, a sixth step of exchanging the image data for the first and third sub-pixels with each other, and a seventh step of outputting the image data rearranged by the third to sixth steps to the liquid crystal panel such that the image data synchronize with the scan signals according to the second step.
