Abstract: A multilayer polymer thin film includes an anti-reflective coating directly overlying a reflective polarizer stack. The reflective polarizer stack includes alternating first and second polymer layers, where the first layers include an isotropic polymer thin film and the second layers include an anisotropic polymer thin film. The anti-reflective coating (ARC) includes alternating third and fourth layers, where the third layers include an isotropic polymer thin film or an anisotropic polymer thin film and the fourth layers include an isotropic polymer thin film. The multilayer polymer thin film may be formed by co-extrusion where the reflective polarizer stack and the anti-reflective coating are formed simultaneously.
