Abstract
A display device includes a light source array including a plurality of light sources where at least one of the plurality of light sources is selectively driven, a spatial light modulator for modulating light from the light source array to form image light, a focusing optical system for focusing the image light formed by the spatial light modulator at a position in a predetermined eye box, a micro mirror array arranged in an optical path formed in the focusing optical system and including a plurality of mirror cells. The plurality of mirror cells are controlled to be in an ON state in that light is reflected in a direction toward an inside of the eye box or to be in an OFF state in that light is reflected in a direction toward an outside of the eye box.
