Display device and projector for modulating irradiation light to form an optical image and displaying the optical image having a spatial light modulation element with plural sub-pixels

摘要

A display device for modulating irradiation light with a spatial light modulation element to form an optical image, and displaying the optical image, includes a light source for emitting the irradiation light including four kinds of colored light having wavelength ranges, a temporal colored light separating section that spatially separates the irradiation light by the wavelength range to generate first irradiation light, and second irradiation light alternately 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, and a spatial light modulation element provided with a plurality of sub-pixels, capable of independently modulating every sub-frame period.
