Abstract
A liquid crystal display assembly includes a liquid crystal display, and a surface light source device that illuminates the liquid crystal display from a back surface. The surface light source device includes a housing including a bottom plate, a light source that is arranged on the bottom plate and illuminates the liquid crystal display, and a plurality of radiator fins arranged at a spacing from each other. Each of the radiator fins includes a first fin portion formed by bending a part of the bottom plate in a direction away from the liquid crystal display, the first fin portion extending substantially perpendicularly to the bottom plate, and a second fin portion formed by bending a part of the first fin portion in a direction away from the liquid crystal display, the second fin portion extending substantially parallel to the bottom plate.
