Summary:A backlight unit for a liquid crystal display device (LCD), and an LCD including the same are disclosed. One embodiment of the backlight unit includes an organic light emitting element in which the efficiency of light extraction is improved without decreasing productivity to achieve high brightness and a low consumption power. The backlight unit includes a substrate, an organic light emitting element formed on the substrate, and an encapsulating member attached to the substrate to enclose the organic light emitting element. The backlight unit further includes a scattering film on one of surfaces of the substrate, the organic light emitting element and the encapsulating member to prevent light emitting from the organic light emitting element from being totally reflected.
