Abstract
A field sequential type liquid crystal display apparatus includes a liquid crystal display device in which unit-color image data of different colors are sequentially written in display elements during the period of one frame composed of three continuous fields, and an illuminating unit placed at the back of the liquid crystal display device to sequentially emit light beams having colors corresponding to the colors of the unit-color image data in accordance with the sequential write of the unit-color image data. The illuminating device is selectively controlled to sequential turn-on of colors, total turn-off by which the emission of all the light beams is stopped, or total turn-on. A semitransparent reflecting film is formed between the liquid crystal display device and the illuminating unit.
