<p>Existing thin high penetrating polarization film tends to have low durability. To solve this problem, the present invention provides a polarization film of consecutive webs, which include a polyvinyl alcohol-based resin comprising kalium and oriented iodine, wherein a thickness of the polarization film is less than or equal to 7μm, a group penetration ratio of the polarization film is equal to or greater than 44.0%, and a mole ratio (I/K) of an iodine element to a kalium element included in the polarization film is equal to or greater than 1.8.</p> |
