The utility model relates to a backlight module, include: install circuit board, the reflecting cavity of a plurality of luminescence units and be embedded into the inside leaded light component of reflecting cavity, its characterized in that, reflecting cavity's the bottom fretwork portion that is provided with partial at least, the light emitting area of luminescence unit with the fretwork position is put relatively. The circuit board is provided with the through -hole, reflecting cavity's bottom be provided with with reflecting cavity is the connecting piece of a body structure, will the connecting piece of reflecting cavity bottom directly assembles in the through -hole of circuit board, the area that the connecting piece stretches out the through -hole outside is greater than the positioning between circuit board and the reflecting cavity is realized to the area of through -hole, can effectively prevent the light leak problem. The leaded light component is a dull polish translucent PC material, and the i
