Abstract: The present disclosure relates to a field of display technology and discloses a backlight module and a display device. The backlight module comprises: a backplate comprising a bottom plate and side plates, which form a mounting recess; an optical film positioned in the mounting recess; at least two supporting bars positioned between the bottom plate and the optical film and arranged crosswise, wherein each two supporting bars are fastened to each other and each of the supporting bars is fastened on the bottom plate. In the above backlight module, a mechanical strength of the backplate of the backlight module may be increased due to the supporting bars mounted on the bottom plate and arranged crosswise, and a resistance to bending of the backplate is thus improved. Further, as the used supporting bars have a bar-shape structure and are arranged crosswise without covering the overall surface of the backplate, the weight of the backlight module is increased by a smaller amount than the existing backlight module with an increasing strength of the backplate. Thus, the backlight module has a high strength and a light weight.
