Abstract: A color-filterless liquid crystal display device is capable of realizing a full color without any color filters in sub-pixels of the display. In the device, a three primary color selector is arranged at a light incident surface of a light guide to generate three primary color light beams sequentially, color-by-color. The three primary color selector may be provided on one or more sides of a light guide in a back light, or it may be provided above the back light. Use of a color filter is eliminated to reduce a manufacturing cost and improve a process yield and an aperture ratio of the device. Also, independent light sources corresponding to three primary colors are replaced by a single light source, so that light utilization efficiency may be optimized and a slim-type LCD may be provided.
