Abstract
A multilayer optical compensation film includes at least one optically anisotropic first layer and at least one optically anisotropic second layer. The indices of refraction of the first layer satisfies the relation nx1≧ny≧nz. The second layer includes amorphous polymer with a glass transition temperature above 160° C., and the indices of refraction of the second layer satisfy the relations |nx−ny|<0.001 and nz−(nx+ny)/2>0.005.
