A backlight assembly includes a lamp, a light guide plate, a receiving container and a lamp holder. The lamp generates light. The light guide plate has a light incident face through which the light generated by the lamp enters the light guide plate. The light guide plate guides the light. The receiving container has a base plate and sidewalls protruding from the edge portions of the base plate to define a receiving space for receiving the lamp and the light guide plate. The lamp holder holds an end portion of the lamp and includes a buffer portion. When an impact is applied to the backlight assembly, the buffer portion absorbs the impact to prevent damages to the lamp and the light guide plate.
