Backlight module

The utility model relates to the technical field of panels. The utility model relates to a backlight module. The metal sheets are arranged on the first hanging lug piece, the second hanging lug pieceand the third hanging lug piece, the hanging lug pieces attached to the metal sheets are fixed through adsorption force generated between the magnets and the metal sheets, and therefore the upper brightness enhancement film, the lower brightness enhancement film and the diffusion film are indirectly fixed through the fixed hanging lug pieces, and the diaphragms are not prone to moving. The first hanging lug piece, the second hanging lug piece and the third hanging lug piece are bent in the same direction, the situation that in the prior art, the hanging lug pieces and the membrane are locatedon the same horizontal plane is replaced, the upper edge width value, the left edge width value and the right edge width value in the backlight module can be further reduced, and therefore the designrequirement for a narrow fr
