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/(m<SUP>2</SUP>.day) in terms of the thickness of 80 mum. 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.
