ABSTRACT:
A liquid crystal display device employs a white sub-pixel among RGBW-4 sub-pixels as a view control component to realize a narrow viewing angle or a wide viewing angle in a fringe field switching mode. The LCD device comprises gate lines and data lines crossing each other to define RGBW sub-pixels on a first substrate, a thin film transistor formed at each crossing of the gate and data lines; a first common electrode in each region of the RGBW sub-pixels, a pixel electrode connected to the thin film transistor and insulated from the first common electrode, the pixel electrode having at least one slit, a second substrate attached to the first substrate, wherein the first and second substrate face each other with a liquid crystal layer interposed therebetween, and a second common electrode on the second substrate and corresponding to each W sub-pixel.
