摘要：
An optical film, suitable or use in, or as a component of, an image display device or apparatus (for example, a LCD device or a polarizer assembly), comprises a hydrogenated vinyl aromatic/conjugated diene block copolymer that has a near zero optical retardation at all light incidence angles (measured using incident light at a wavelength of 633 nanometers).
