Abstract
A direct backlight module includes a light optical plate, a plurality of point light sources, and a reflective member. The optical plate includes a light input surface and a light output surface opposite to the light output surface. The point light sources are positioned between the optical plate and the reflective member. The reflective element forms a plurality of curved reflective surfaces corresponding to the point light sources. Each curved reflective surface is a substantially spherical depression, and each point light source corresponds to a center of each spherical depression defined by one of the curved reflective surfaces.
