A driving device and method of a liquid crystal display are provided to make the operation speed fast by generating data of four colors at the same time regardless of the algorithm by using a data conversion unit including one division unit. A driving device of a liquid crystal display includes a liquid crystal panel(102) having sub pixels of four colors; a data driver(104) for supplying a video data signal to each sub pixel; a gate driver(106) for supplying scan pulse to the sub pixels; a data conversion unit(110) extracting plural white data by using source data of three colors(RGB) input from the outside, selecting one of the white data extracted according to a selection signal(sel) input from the outside, and converting the three color source data into four color(RGBW) data; and a timing controller(108) supplying the four color data output from the data conversion unit to the data driver and controlling the gate and data drivers.
