Abstract
A method of displaying a color video picture according to a field sequential process is provided. A display device displays an image comprising a matrix of pixels. One frame image is composed of four field images ranging from a first field image to a fourth field image. With four adjacent pixels handled as one unit, the colors R, G, B, W of illuminating lights applied to the pixels in each unit are different from each other, and the arrangement of the colors is successively switched or changed in each field period. Information representing the colors R, G, B, W separated from a video signal is displayed sequentially in successive fields at positions corresponding to the colors of the illuminating lights applied to the pixels and times at which the illuminating lights are applied to the pixels.
