Disclosed is an LCD for displaying colour images including a liquid crystal unit for transmitting selectively light rays through pixels under the control of video signals, a video signal supply device for supplying the video signals controlling the pixels of the liquid crystal unit, a monochromatic light ray supplying device for supplying a red, green or blue light ray necessary to present colours under the control of the video signals, and a light supplying device for supplying white light to the monochromatic. The monochromatic light ray supplying device is structured so as to separate the white light provided by the light supplying device into the red, green and blue light rays which light rays are selectively supplied to the pixels of the liquid crystal unit as the video signals control the pixels of the liquid crystal unit.
