1. A backlight module, comprising:
a first optical element;
a second optical element and a third optical element that sequentially face away from the first optical element; and
a fixing frame arranged around the first optical element;
wherein the second optical element and the third optical element are both provided with a plurality of hanging lug holes; and the first optical element is not provided with a hanging lug hole;
the fixing frame comprises:
a first edge frame and a second edge frame that are oppositely arranged, and
a third edge frame and a fourth edge frame that are oppositely arranged,
wherein a side of each edge frame of the fixing frame facing the first optical element is provided with a plurality of adhesive tapes that are independent of each other and extend in an extension direction of the each edge frame, the first optical element is fixed to the fixing frame through the adhesive tapes, and the fixing frame is made of metal;
wherein with a plurality of hanging lugs arranged on the fixing frame passing through the corresponding hanging lug holes, the second optical element and the third optical element are fixed to the fixing frame;
recess regions for the hanging lugs to be fixed are reserved on each edge frame; on any edge frame, there are at least a first recess region and a second recess region that are arranged at two ends of the edge frame respectively; at least one adhesive tape is arranged in space between the first recess region and the second recess region; and at least part of the adhesive tape is attached to the first recess region, and at least part of the adhesive tape is attached to the second recess region.
