Abstract: A liquid crystal display includes a liquid crystal display panel having a first substrate and a second substrate. An upper polarizer is disposed on an outer surface of the first substrate. A viewing angle control film is disposed on the upper polarizer. The viewing angle control film includes a polarizing layer having a transmission axis substantially parallel to a transmission axis of the upper polarizer and a phase retardation layer including a birefringence material having an optical axis with a poloidal angle of about 40 degrees to about 75 degrees.
