Abstract: A stereoscopic display including a backlight module, a display panel, a light-controlling element and a switching element is provided. The backlight module includes a light source and a light guide plate. The light guide plate has a light incident surface and a light emitting surface. The light-controlling element is disposed between the display panel and the light guide plate. The light-controlling element includes a plurality of light-controlling surface groups. Each of the light-controlling surface groups has a first surface and a second surface opposite to each other. At least one of the first surface and the second surface inclines with respect to the light emitting surface by over 90 degrees. The switching element is configured to switch between a light transmitting mode and a light scattering mode.
