A display system capable of raising limits on the response speed of the spatial light modulator and the rate of pulse-width modulation signal transfer is provided at a low cost. The display system comprises: a color switch filter unit used in the sequential color separation of white light from the light source; a spatial light modulator which is illuminated by lights of plural color elements from the color switch filter unit and generates image lights of the respective color elements; and an intensity switch filter unit for switching three or more intensity levels of the respective lights of plural color elements, being separate from the color switch filter unit.
