Abstract: The present disclosure relates to a light guide plate, a backlighting module and a liquid crystal display device. The light guide plate comprises a light guide plate body and an optical waveguide layer located within the light guide plate body. According to technical solutions of the present disclosure, the optical waveguide layer can modulate stray light in the light guide plate into collimated light, such that the collimated light is emitted out from a light exit side of the light guide plate. As compared with an existing approach, with the light guide plate of the present disclosure, a loss of incident light of the light guide plate is reduced, an optical efficiency of the backlighting module is improved, and thereby a display quality of the display device is promoted.
