A display device including a main body and a support assembly is provided. The main body includes a first body and a second body that are pivotally connected to each other. A first display surface is located on the first body, and a second display surface is located on the second body. The first body and the second body are adapted to relatively pivot, so that an edge of the first body and an edge of the second body substantially jointly constitute a bending segment. The support assembly is movably connected to the main body. When the support assembly is unfolded from the main body, one end of the bending segment and the support assembly are adapted to jointly support the main body on a surface.
