Abstract:
Provided is an optical film which is resistant to repelling, bright dots, irregularity, and the use of such an optical film in a liquid crystal display leads to high front contrast, reduced grayscale inversion, and a reduced difference between a front image and an oblique image in grayscale reproducibility and color. The optical film including a first optically anisotropic layer; and a second optically anisotropic layer on the first optically anisotropic layer, wherein the first optically anisotropic layer is a layer of liquid crystal compounds aligned and fixed by polymerization, and the surface tilt angle of molecules of the liquid crystal compound is in a range of 5° to 80° at a site in contact with the second optically anisotropic layer.
