1. A polarization film comprising:

  • at least a planar polarization layer that extends in a plane and is stretched along a predetermined direction to realize polarization, the predetermined direction being in the plane of the planar polarization layer in which the planar polarization layer extends, andan adhesive layer that is attached on a surface of the planar polarization layer and capable of being affixed onto a base, wherein the adhesive layer and the planar polarization layer are bonded together in the plane of the planar polarization layer, and the adhesive layer has a maximal shrinkage resistance in the predetermined direction in the plane of the planar polarization layer.
