A backlight module includes a base, a plurality of point light sources distributed on the base and a light guide plate. Each of the point light sources includes a transparent cover and a light-emitting unit received in the cover. The transparent cover includes an inwardly curved light emitting top surface for emitting light from the light-emitting unit. The light guide plate includes an incidence surface disposed facing the point light sources, and an emission surface opposite to the incidence surface. The incidence surface includes a plurality of light diffusion areas spatially corresponding to the respective point light sources.
