    Abstract: A backlight unit includes a light source, a mold frame which accommodates the light source includes at least a first sidewall and an inclined surface protruding and sloping downward from an inner side surface of the first sidewall. A second sidewall may extend from the inclined surface in which the second sidewall is arranged substantially parallel to the first sidewall and has a space therebetween. The support member is disposed on the inclined surface of the mold frame. An optical plate may be disposed on an upper surface of the support member, and the optical plate and the inclined surface of the mold frame define an optical path in a space there between.
