Patent ID: 7220044

Claim:
A backlight module, comprising: a base plate; a first reflector comprising a first reflecting surface facing the base plate; a light source disposed between the base plate and the first reflector, emitting a first initial beam directly onto the first reflecting surface for being reflected by the first reflecting surface to form a first reflecting light beam and a second initial beam being reflected by the first reflecting surface to form a second reflecting light beam, wherein the first reflecting light beam and the second reflecting light beam substantially pass through the base plate in parallel; and a second reflector provided with a second reflecting surface facing the light source and a third reflecting surface opposite to the second reflecting surface, wherein the second reflecting surface and the third reflecting surface of the second reflector are total-reflecting surfaces, wherein the backlight module further comprises a third initial beam from a diffusive plate, the third initial beam is reflected by the third reflecting surface to form a third reflecting light beam, wherein the third reflecting light beam passes through the base plate.
