Abstract
A back light unit includes a lightguide (#204), a lamp (#202) fastened to one side of the lightguide, a U-shaped argentum reflector (#240) which encompasses the lamp, a reflecting sheet (#203) beneath the lightguide and a frame (#210) positioned under the reflecting sheet. The U-shaped argentum reflector and the reflecting sheet, as separate elements, are attached to form a continuous plane parallel to and along the length of the lightguide without resulting in a step arrangement at the connection. Additionally, the U-shaped reflector and the reflecting sheet are manufactured as separate elements each composed of the same or different materials.
