A backlight module, comprising a backlight assembly (10) used for generating a backlight source. An optical film is provided on the upper surface of the backlight assembly (10), and a light shielding layer (20) is sprayed on the periphery of the upper surface of the optical film. According to the backlight module, due to the fact that the light shielding layer (20) is sprayed on the periphery of the optical film, the defects that a black double-faced adhesive tape has complex mechanical cutting process and cannot achieve narrow bezel display in the prior art are overcome, and meanwhile the optical taste of a display product is improved. Also provided is a spray jig (100) used for spraying the light shielding layer (20) of the backlight module, and the spraying precision and the spraying efficiency of the light shielding layer (20) are improved. |
