The invention provides a backlight module. The backlight module comprises a light guide plate, multiple light sources and a rubber frame. The rubber frame includes multiple side walls; and the multiple side walls surround an accommodating space for accommodating the light guide plate and the multiple light sources. The multiple side walls include a first side wall; the multiple light sources are arranged on one side near the first side wall at intervals; and the light guide plate is arranged on one sides, far from the first side wall, of the multiple light sources. The first side wall extends to the accommodating space to form a bearing wall. The bearing wall covers the multiple light sources and partially covers the light guide plate. Multiple reinforcing parts extend from the surface of the bearing wall on one sides of the light sources to the light sources for supporting the bearing wall, and are arranged among the multiple light sources at intervals. Compared with the prior art, as the multiple reinforcing parts extend from the surface of the bearing wall of the rubber frame, the reinforcing parts can achieve a reinforcing effect to relieve the deformation or rupture of the bearing wall when the bearing wall is stressed, and the improvement of whole structure stability of the backlight module is facilitated.
