Abstract
A backlight assembly includes a receiving container and a light guiding plate. The light guiding plate includes a protrusion formed on a side portion facing a sidewall of the receiving container. When the light guiding plate drifts in the receiving container, the sidewall of the receiving container makes contact only with the protrusion extending from the light guiding plate, so that a contact area between the light guiding plate and the receiving container is reduced. Thus, a noise induced by friction between the light guiding plate and the receiving container may be prevented and a manufacturing yield thereof is enhanced.
