Zusammenfassung:	A backlight module is disclosed, which includes a substrate, a light emitting device disposed on the substrate, two elastic arms disposed on opposite sides of the light emitting device, and a light guide plate. Each elastic arm has a connecting portion and a bending portion. The connecting portion connects to the light emitting device. The bending portion is extended from the connecting portion and is bent, and a gap is formed between the bending portion and the light emitting device. Each bending portion has a first coupling portion. The light guide plate has light input surface. The light input surface has a cavity to locate the light emitting device. The light guide plate further includes two second coupling portions disposed on opposite sides of the cavity. The first coupling portions would couple to the second coupling portions to position the light emitting device and the light guide plate.
