Abstract
Since a backlighting apparatus 1 for liquid crystal display is constituted such that a light guiding plate 2 and a frame 3 are molded together as a single unit provided with a deformation relaxation design, an attaching unit and parts, such as attaching feet and screws, for attaching the light guiding plate 2 to the frame 3 are not required, thereby making it possible to reduce the thickness and size of the backlighting apparatus 1 for liquid crystal display which has been restricted by the sizes of these parts.
