An optical element includes a microlouver including transparent layers and light absorbing layers alternately disposed, the light absorbing layers constraining the extent of the direction in which light passing through the transparent layers exits, and a diffusion layer provided on the microlouver. The angle of the field of view varies in such a way that the angle of the field of the view light passing thorough the peripheral area of the optical element is smaller than the angle of the field of view of light passing thorough the central area of the optical element. |
