<P>PROBLEM TO BE SOLVED: To provide a field sequential liquid crystal display device in which a desired chromaticity of the white level can be easily achieved and in which fluctuations in the white level caused by fluctuation factors such as temperature characteristics can be suppressed. <P>SOLUTION: A light source 1 comprises red, green, blue and white LEDs 4, 5, 6, 7. The white LED 7 includes a blue LED covered with a yellow fluorescent material. One field is divided into display subfields of red, green, blue and white fr, fg, fb, fw. Only the red LED 4 turns on in the red display subfield fr, only the green LED 5 turns on in the green display subfield fg, only the blue LED 6 turns on in the blue display subfield fb, and only the white LED 7 turns on in the white display subfield fw. A shutter 2 is controlled in each subfield based on sub-image data of each color. <P>COPYRIGHT: (C)2004,JPO |
