The invention discloses a backlight module, a television with the backlight module and a display device with the backlight module. The backlight module comprises a rubber frame and a plurality of optical diaphragms arranged above the rubber frame in an overlapped mode. A plurality of hanging lugs which protrude outwards are arranged on the periphery of the optical diaphragms. A bearing concave portion corresponding to the hanging lugs is arranged on the rubber frame. Light guide holes are formed in the bearing concave portion and penetrate through the rubber frame. Through arrangement of the light guide holes in the bearing concave portion of the rubber frame, lightproof characteristic of a traditional rubber frame is changed, and backlight can penetrate through the rubber frame and is conducted on the surfaces of the optical diaphragms, so the backlight module is favorable for improving luminance at the positions of the hanging lugs of the optical diaphragms, ensures the luminance at the positions of the han
