Abstract
The utility model discloses a backlight frame, a backlight and a display device. The backlight frame comprises an inner frame and an outer frame. The inner frame is arranged on the internal side edge of the side wall of the outer frame. The internal side of the side wall of the outer frame is provided with a mosaic structure. The inner frame and the outer frame are formed by injection molding, so that the inner frame and the mosaic structure of the outer frame can be combined together. By arranging the mosaic structure on the internal side of the side wall of the outer frame to increase the bonding strength between the outer frame and the inner frame, holes are prevented from being arranged in the outer frame and the situation that the backlight leaks light is avoided.
