Abstract
Provided is a display device, including: a light shielding film including a plurality of fixed apertures, each allowing passage of light; a lens arranged above the plurality of fixed apertures; a plurality of shutters, which are arranged between the light shielding film and the lens and correspond to the plurality of fixed apertures, respectively, for controlling passage and blocking of the light; and a drive portion for driving each of the plurality of shutters to move between a position above each of the plurality of fixed apertures and a position retracted from each of the plurality of fixed apertures. The plurality of fixed apertures each have an elongated shape including a long-side direction and a short-side direction. The lens has a light refractive power that is larger in the short-side direction than in the long-side direction.
