<p>A transparent polymer film satisfying Re<5, |Rth|<20, |Re(700)−Re(400)|<5, |Rth(700)−Rth(400)|<20, |Re(10%)−Re(80%)|<5, and |Rth(10%)−Rth(80%)|<15, and having a moisture permeability of at least 500 g/(m2·day) in terms of the thickness of 80μm. The file is excellent in moisture resistance and having a small amount of optical anisotropy and capable of being directly stuck to a polarizing film.</p> |
