PHASE DIFFERENCE FILM, STACKED POLARIZATION FILM AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

It is an object to provide a phase difference film that can achieve a wide viewing angle with a high level in the case where it is applied to a liquid crystal display device, a stacked polarization film that can realize a wide viewing angle by using the phase difference film, and a liquid crystal display device that is made highly performable to aim at a wide viewing angle in particular. A structure provided with both a structural birefringence and a molecular orientational birefringence is used as the phase difference film. Concretely, the phase difference film includes a repeatedly multiple-layer structure (13) in which at least two kinds of layers (11, 12) with different average refraction indices are a structural unit, wherein at least one of the two layers is an optically anisotropic layer.
