Abstract: The invention provides an outer frame for a display device, a backlight module and an LCD device. The outer frame includes at least two sections; the sections include a mounting section for arranging the light source of the backlight module. In the invention, because the outer frame of the backlight module is divided into multiple sections, and one of the sections is used as a mounting section for arranging the light source, the light source is arranged on the mounting section of the outer frame when being assembled, and the required assembling action is simple in the assembling process; thus, the step of assembling the light source on the backplane or aluminum extrusion is omitted, and the assembling technology is simplified. In addition, when replacing the light source of the backlight module, only the mounting section of the outer frame is removed, and then the light source is replaced on the outer frame. Thus, most components of the backlight module are exposed into air because many components are removed, causing dust to enter inside the backlight module to affect the optical performance of the backlight module can be avoided, the replacement process of the light source can be simplified, and the stability of the LCD device can be increased.
