Patent ID: 7772534

Claim:
A display device for modulating irradiation light with a spatial light modulation element to form an optical image, and displaying the optical image, comprising: a light source for emitting the irradiation light including four kinds of colored light having wavelength ranges within a visible range and different from each other; a temporal colored light separating section that temporally separates the irradiation light including the four kinds of colored light by the wavelength range to generate first irradiation light including first colored light and second colored light, and second irradiation light including third colored light and fourth colored light alternately and every sub-frame period; a spatial colored light separating section that spatially separates the colored light included in each of the first irradiation light and the second irradiation light to generate the first colored light and the second colored light in a first sub-frame period and to generate the third colored light and the fourth colored light in a second sub-frame period temporally adjacent to the first sub-frame period; and a spatial light modulation element provided with a plurality of sub-pixels, capable of independently modulating every sub-frame period one of a set of the first colored light and the second colored light and a set of the third colored light and the fourth colored light respectively entering two of the sub-pixels disposed adjacent to each other.
