<p>A transparent polymer film, which satisfies 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 exhibits a moisture permeability in terms of a film thickness of 80 mum of 500 g/(m^2day) or more. The above film is excellent in the resistance to moisture, is reduced in optical inisotropy, and can be directly pasted together with a polarizing film.</p> |
