    Abstract: A backlight module, a base used therein, and a manufacturing method thereof are provided. The backlight module includes a base and a slice-shaped circuit. The base has a back plate including a plate portion and a mezzanine portion. The mezzanine portion is parallelly offset from the plate portion, and the initial position of the mezzanine portion becomes an opening on the plate portion. Because the mezzanine portion is parallelly offset from the plate portion, a containing space is formed between an inner side of the mezzanine portion and the plane of the plate portion. A side of the mezzanine portion and a side of the plate portion corresponding to the opening together form a first slit. The slice-shaped circuit is inserted into the containing space through the first slit and stays between the plate portion and the mezzanine portion.
