Abstract: A polarizing film includes a polarizing layer and a twisted liquid crystal layer. The twisted liquid crystal layer includes liquid crystal molecules arranged to have different degrees of inclination from each other with respect to a transmission axis of the polarizing layer in a thickness direction. A top tilting angle is about 64° to about 75°; a bottom tilting angle is about 135° to about 145°, and the twisted liquid crystal layer has a thickness of about 2.5 μm to about 3 μm in the thickness direction.
