The present disclosure relates to liquid crystal display technology, and more particularly to a double-sided display. The double-sided display includes a first display panel, a second display panel parallel to the first display panel, and a backlight module between the first display panel and the second display panel. The backlight module includes a first optical film and a second optical film respectively arranged at internal sides of the first display panel and the second display panel, and a light guiding layer between the first optical film and the second optical film. The light guiding layer includes a first dot reflective layer and a second dot reflective layer parallel to each other, at least one light reflecting component and a light source arranged within the light reflective component. The first dot reflective layer, the second dot reflective layer and the light reflective components cooperatively form a light guiding chamber. The double-sided display includes the edge-type backlight without adopting a light guiding plate. The light beams may be guided via the air such that the double-sided display may be thinner and lighter.
