A display device includes a light modulating medium layer, a corner cube array and a reflective electrode layer. The corner cube array is provided on one side of the light modulating medium layer and includes multiple corner cubes as its unit elements. The reflective electrode layer is provided on the corner cube array and includes multiple reflective electrodes that are spaced apart from each other and that are used to apply a voltage to the light modulating medium layer. When the display device is viewed from over the corner cube array, an arrangement pattern of the corner cubes matches an arrangement pattern of the reflective electrodes in at least one direction.
