The present invention provides a flat panel display device, a stereoscopic display device, and a plasma display device. The flat panel display device includes a backlight system and a display panel, the backlight system including a light source, a light homogenization mechanism, and a back frame; the back frame carries the light source and the light homogenization mechanism, the light homogenization mechanism guiding light from the light source to a light incidence surface of the display panel; the back frame includes at least two primary assembling pieces and the two primary assembling pieces are connected through direct or indirect joining; the at least two primary assembling pieces that directly joined or indirectly joined are set in mutual rotation symmetry of a predetermined angle with respect to each other. The flat panel display device, the mold for making back frame of flat panel display device, the backlight system, the stereoscopic display device, and the plasma display device of the present invention, through providing at least two primary assembling pieces that are set in mutual rotation symmetry of a predetermined angle with respect to each other, make it possible for one set of mold to be shared by various primary assembling pieces so as to reduce the cost of mold and thus lowering the manufacturing cost.
