Claim 17:
18. A polarization film, comprising:
a base substrate comprising: a folding area in which a folding axis is defined, a non-folding area neighboring the folding area, wherein a stretched axis is defined in the base substrate to be in an angle of less than about 45° with respect to the folding axis, and the base substrate is foldable with respect to the folding axis and has been stretched along the stretched axis; and
a deformation portion located at an edge of the base substrate, wherein the deformation portion is a portion deformed by heat,
wherein the deformation portion has a greater width in the non-folding area than a width thereof in the folding area.
