There is provided a condensing film for an LCD backlight unit. The condensing film includes a base member unit; a condenser unit disposed in an upper surface of the base member unit and having unit lens groups sequentially arranged thereon, each of the unit lens group being composed of a combination of at least two lenses that are different in shape; and a reflector unit disposed in a lower surface of the base member unit and composed of an opening through which light passes and a reflective surface from which the light reflects. The condensing film configured thus may be useful to solve the problems regarding the viewing angle and the uniformity in brightness of a screen since the condensing film has a more moderate distribution of emitted light than the conventional condensing films.
