Backlight module

A backlight module, comprising:

• a bottom plate with a first loading surface and a recess adjacent to a side of the first loading surface, the recess comprising a second loading surface and a reflective surface, the reflective surface being located between the first loading surface and the second loading surface, and the reflective surface being inclined to the first loading surface and the second loading surface;
• a light guide with a light inputting surface and a light outputting surface that are connected to each other, the light guide being disposed on the first loading surface of the bottom plate, one side of the light guide covering the reflective surface which is inclined such that the light inputting surface is located above the recess, and the light outputting surface facing away from the bottom plate;
• and
• a light source assembly with at least one light emitting surface, the light source assembly being disposed on the second loading surface, the light emitting surface facing the light inputting surface and the reflective surface, the light emitting surface comprising a side edge away from the second loading surface, the light source assembly being disposed inside the recess such that the side edge of the light emitting surface is not higher than the light outputting surface of the light guide.
