Abstract: Disclosed is a display device that can uniformly transmit light emitted from a light source to the entire display panel without using a light guide plate. The display device includes a display panel, a backlight assembly supplying light to the display panel, and a lower cover receiving the backlight assembly. The backlight assembly includes a light source, a circuit board mounted with the light source, and a reflection cover coupled to the circuit board to reflect light emitted from the light source and formed of a bendable plate type member.

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.
