Abstract
A display device which can reproduce kinematic parallax and express a high sense of realism without using image display means are provided. The display device includes an image display unit having a stripe structure having subpixels of a plurality of colors disposed so that subpixels of the same color are arranged in a first direction and enabling an observer to observe, through an aperture, an image formed by pixels, each pixel being constituted by the subpixels of a plurality of colors. The aperture has a shape that has been smoothed to reduce a number of corners in which areas of the subpixels of the plurality of colors which can be seen through the aperture are uniform, and in which a numerical aperture decreases along a second direction orthogonal to the first direction. A plurality of the apertures are provided so as not to overlap with each other.
