Abstract

A color display device including: at least one spatial light modulation element forming a display picture by modulated light obtained by modulating illumination light, a color sequential light generation device changing in a time series the illumination light or the modulated light into multiple groups of different color lights in one frame of a display period of the display picture, a control device controlling the spatial light modulator, and a color sequential light generation device based on the input picture data. The control device controls the spatial light modulator and the color sequential light generation device to change the ratio of the display time of each color of the reflected light time-shared in the display period of the frame depending on the character and/or the set value of the input picture data.
