Abstract

A display device is disclosed. The display device includes a backlight module, a display panel, and a second viewing angle control layer. The backlight module includes: a back plate; a first light plate, where a hollowed region is defined in a center of the first light plate; a first viewing angle control layer disposed on the first light plate and including multiple first grid lines; and a rotating assembly, disposed in the hollowed region and configured to control the first viewing angle control layer to rotate in a direction parallel to a plane in which the display panel lies. The second viewing angle control layer is arranged on the first viewing angle control layer, and includes multiple second grid lines. An orthogonal projection of the second viewing angle control layer on the bottom plate overlaps an orthogonal projection of the first viewing angle control layer on the bottom plate.
