A backlight module (100) includes a light source (120) for emitting light therefrom, and a light guide plate (110). The light guide plate includes a light exit surface (111), a bottom surface (112) opposite to the light exit surface, a receiving hole (113) defined in the bottom surface with the light source received therein, a first reflecting surface (115) in the receiving hole facing away from the light exit surface and configured for reflecting the light emitted from the light source, a light incidence surface (116) in the receiving hole, a recess (114) defined in the bottom surface, and a second reflecting surface (117) arranged in the recess. The second reflecting surface faces toward the light exit surface and the first reflecting surface. The second reflecting surface is configured for directing the reflected light from the first reflecting surface to the light exit surface.
