The invention discloses an optical fiber network board laser light source which comprises a laser light source body, dispersion optical fibers, a network structure and an optical fiber network fixing and encapsulating structure. The whole dispersion optical fibers can emit light. The network structure is braided by the dispersion optical fibers. The dispersion optical fibers are arranged according to size and uniformity requirements of a backlight source and a calculated special structure to form the optical fiber network which emits light uniformly, and the specially-designed encapsulating structure is used to encapsulate the braided dispersion optical fiber network into an optical fiber network board which emits light uniformly. The laser backlight source which is good in light emitting uniformity, optionally-variable in shape, low in cost and convenient in scale production, the backlight sources of current liquid crystal televisions can be replaced by the laser backlight source, low-cost laser full-color display is achieved, and the laser backlight source can be used as specially required laser lighting light source.
