Abstract
The present invention provides a stereoscopic display, which comprises a backlight, a display panel, a phase delay film arranged at a light-exiting side of the display panel, and a visual angle adjusting baffle arranged between the backlight and the display panel and parallel to the display panel for adjusting a vertical or horizontal stereoscopic visual angle of the stereoscopic display. The shading strips of the visual angle adjusting baffle can be reflective strips which can reflect light from the backlight arriving at the reflective strips back to the backlight, and the light reflected by the reflective strips to the backlight can enter the display panel after passing through the transparent strips in the visual angle adjusting baffle, thus improving display brightness of the stereoscopic display.
