Claim Text:
1. A display device that displays an image, comprising: a light source that emits light; an aperture stop array that includes a plurality of aperture stops which respectively limit a transmission range of the light; a lens array that includes a plurality of lenses which are disposed corresponding to the plurality of aperture stops respectively, and focus the light transmitted through the plurality of aperture stops respectively; a deflecting unit that deflects a travelling direction of the light focused by the plurality of lenses respectively; a spatial light modulator that is illuminated by the light deflected by the deflecting unit, and modulates the illumination light; a detector that detects an observer who observes the spatial light modulator; and a controller that calculates a position of a pupil of the observer based on a detection result by the detector, calculates a relative position of the display device and the pupil of the observer based on the calculated position of the pupil, and changes an aperture amount of the plurality of aperture stops and a deflecting amount of the deflecting unit based on the calculated position of the pupil and the calculated relative position.
