Abstract:
An optical film comprising a first domain of a polymer composition and a second domain disposed inside the first domain, wherein the second domain is a bubble having a morphology anisotropy, and the mean alignment direction of the main chain of the polymer molecule in the first domain differs from the mean direction of the major axis of the second domain, is capable of contributing toward display performance unification and body thickness reduction of an image display device.
