Claim 21:
22. 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, 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, and the deformation portion comprises a thermally denatured portion and a color shifting portion arranged from the edge of the base substrate to a center portion thereof when viewed from a plan view in a thickness direction of the polarization film,
wherein the folding area has a width less than a width of the non-folding area.
