Abstract

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 includes a light source, a light homogenization mechanism, and a back frame. The back frame carries the light source and the light homogenization mechanism and the back frame includes at least two assembling pieces. The at least two assembling pieces are joined to form the back frame. The back frame further includes a bracing piece that is fixed to the assembling pieces, wherein the assembling pieces are mountable to at least two different positions of the bracing piece in a lengthwise direction of the bracing piece and the bracing piece is mountable to at least two different positions of the assembling pieces in a lengthwise direction of the assembling piece. The present invention has a simple structure of mold for the back frame, reduces the cost of back frame mold, saves the material used for back frame, and thus lowers down the manufacturing cost. Further, by making the mounting position of a bracing piece to an assembling piece adjustable in a two-dimensional manner, a single bracing piece may meet different needs for mounting so as to further reduce the manufacturing cost.
