Abstract

The backlight module includes a light source, a diffusion plate, a substrate and a reflector. The diffusion plate has a light incident surface and a light emitting surface at two opposite sides. The reflector is positioned on the light incident surface and faces the light source. The substrate includes an aspherical surface, a reflective film formed on the aspherical surface, and a recess defined in the aspherical surface. The reflective film faces the light incident surface. The light source is received in the recess. Light emitted from the light source is reflected to the reflective film by the reflector, then reflected to the light incident surface of the diffusion plate, and exits from the light emitting surface of the diffusion plate.
