A backlight unit for a liquid crystal display panel includes a diffusor that diffuses light emitted from a front surface thereof, a reflective plate that reflects light toward a rear surface of the diffusor; and a collimator that collimates the light emitted from the front surface of the diffusor toward the liquid crystal display panel. The collimator includes a base layer that refracts the diffused light from the diffusor toward the liquid crystal panel, a collimating layer of lenses disposed along two perpendicular directions on a front surface of the base layer, and a reflective pattern on a rear surface of the base layer along a boundary of each of the lenses, the reflective pattern exposing an aperture portion of the base layer facing each of the lenses.
