A polarization film includes: a polarization layer; a first light compensation film arranged on one side of the polarization layer and including a positive A plate; and a second light compensation film arranged on one side of the first light compensation film and including a positive C plate. A value of n(+C)−n(+A) is positive at a wavelength of 450 nm and negative at a wavelength of 650 nm. Here, ne(+A) denotes an extraordinary refractive index of the first light compensation film and n(+C) denotes an extraordinary refractive index of the second light compensation film.

Polarization film and display apparatus including the same

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.
