ABSTRACT:
The object is to provide a display device that is capable of displaying an image with high luminance and a wide color reproduction range under simple control. The display device includes a light source device that emits first to fourth illumination lights, a spatial light modulator that modulates the illumination lights, and a controller. The controller allows the first and the second illumination lights to time-sequentially enter an identical illumination area of the spatial light modulator, and allows the third and the fourth illumination lights to individually enter the spatial light modulator so as to avoid them from being superimposed on the first and the second illumination lights.
