Abstract: A backlight assembly and a liquid crystal display having the same are provided. The backlight assembly includes a plurality of LED packages mounted on a substrate, and a lens unit that seals the LED packages. The lens unit includes a plurality of convex lenses arranged to partially overlap with each other or arranged proximate to each other. Light emitted from LED units in the LED packages is diffused by the interface between the lens unit and another material, such as air, to provide light incident on a light guide plate.
