The invention provides a framework, a backlight module and a display device, and belongs to the technical field of manufacturing of display devices. The framework, the backlight module and the display device resolve the problem that the edge of an existing liquid crystal display device can not avoid light leakage. The framework is used for fixing a liquid crystal display panel and the backlight module and provided with a buffering part between an edge frame extending into the display device and a light outlet surface of the liquid crystal display panel. The backlight module comprises the framework, and the display device comprises the backlight module. The framework, the backlight module and the display device can effectively prevent the edge of the liquid crystal display device from light leakage.
