Abstract
A backlight assembly includes a receiving container receiving a light guide plate and a lamp and a fixing member holding the light guide plate. The fixing member supports an incident face of the light guide plate, into which a light emitted from the lamp is incident, thereby preventing movement of the light guide plate towards the lamp. Thus, the backlight assembly may fix the light guide plate to the receiving container without reforming the light guide plate, so that the backlight assembly may supply light having uniform brightness to a liquid crystal display panel to improve its display characteristics.
