A back frame (23) of a flat-panel display device (20) comprises: at least a first and a second main splicing piece (231, 232). One end of the first main splicing piece (231) is provided with at least two splicing parts (2311, 2312). The structure of each splicing part (2311, 2312) is fitted to one end of the corresponding second main splicing piece (232). The first main splicing piece (231) is spliced with one end of the corresponding second main splicing piece (232) through one splicing part (2311, 2312). Also provided are a mold of the back frame (23), a manufacturing method of the back frame (23), and a back frame mold of a backlight system (21). The structure of the back frame is simple, the cost of the back frame mold can be reduced, and the material of the back frame (23) is saved, so that the cost of the flat-panel display device (20) is reduced.
