Zusammenfassung:	A multi-view auto-stereoscopic display device comprises liquid crystal display screens, parallax light sources and liquid crystal light valves. The liquid crystal display screens are used for alternately displaying a multi-view stereo image. The parallax light sources form ultra thin slit light arrays which are evenly distributed below the liquid crystal display screens. The slit light arrays formed by the parallax light sources are matched with pixels of the liquid crystal display screens in size, wherein each slit light array corresponds to one display screen in width by a plurality of pixels or one pixel or a sub pixel. The liquid crystal light valves are arranged between the liquid crystal display screens and the parallax light sources to realize display of the stereo image both in a plane mode and in a stereoscopic mode. The parallax light sources are parallax backlight sources. According to the multi-view auto-stereoscopic display device, a 'light recover' method rather than a light blocking method is u
