Liquid Crystal Display And Backlight Module Thereof

A backlight module, comprising:

• a bezel;
• a combinational backlight unit, arranged on a lower portion inside the bezel, and the combinational backlight unit comprising a plurality of sub-backlight units spliced at intervals;
• an optical component, arranged on an upper portion inside the bezel and placed on top of the combinational backlight unit at intervals;
• and
• a plurality of dot pattern reflectors, arranged on top of the gap between the adjacent sub-backlight units, respectively for reducing reflectivity of light at the gap;
• wherein
• each of the plurality of sub-backlight units comprises:
• a light guide plate (LGP), comprising an incident surface and a emitting surface, and the emitting surface comprising microstructures;
• a circuit board, arranged on one side of the LGP and supporting the dot pattern reflector;
• a light source, stuck on a lateral side of the circuit board and supplying the incident surface of the LGP with an incident light.
