摘要： A method of manufacturing a birefringent film is provided, by which a birefringent film including a liquid crystal compound birefringent layer and another birefringent layer can be manufactured so as to have a reduced thickness in a reduced number of process steps. In the manufacturing method, a non-liquid crystal polymer birefringent layer that has been subjected to an aligning treatment is used as an alignment layer for a liquid crystal compound. According to the manufacturing method, the process step of separately preparing an alignment layer and the need for the additional alignment layer can be eliminated, thereby allowing the total thickness of the birefringent film to be reduced.

摘要： The present invention relates to an optical film that is excellent in optical properties and can be produced at low cost. In the optical film formed by laminating a transparent polymer film layer and a birefringent layer of a non-liquid crystalline polymer, the birefringent layer satisfies a condition represented by nx≧ny>nz and the in-plane retardation of the transparent polymer film layer is 50 nm or less. In the above formula, nx, ny and nz are the refraction indices in the X-, Y- and Z-axes directions of the birefringent layer, respectively. The X-axis direction is the axial direction in which the refraction index shows a maximum value in the in-plane direction of the birefringent layer, the Y-axis direction is the axial direction perpendicular to the X-axis direction in the plane, and the Z-axis direction is the thickness direction perpendicular to the X- and Y-axes directions.

摘要： The present invention provides a laminated retardation plate that shows an excellent viewing angle property when used in a liquid crystal display, and that can be decreased in thickness. The laminated retardation plate is formed by laminating an optically anisotropic layer (A) made of a polymer having an in-plane retardation of 20-300 nm and a ratio between a thickness direction retardation and the in-plane retardation of not less than 1.0, and an optically anisotropic layer (B) made of a non-liquid crystalline polymer such as polyimide having an in-plane retardation of not less than 3 nm and a ratio between a thickness direction retardation and the in-plane retardation of not less than 1.0. The thus obtained laminated retardation plate shows excellent optical properties, e.g., an in-plane retardation (Re) of 10 nm or more, and a difference between a thickness direction retardation and the in-plane retardation of 50 nm or more.

摘要： The present invention provides a composite birefringent member including a first birefringent layer and a second birefringent layer. The second birefringent layer is formed on at least one surface of the first birefringent layer. In the wavelength range from 400 to 800 nm, a value of Δndx/Δnd550 and a value of Rthx/Rth550 of the composite birefringent member as a whole are different from each other. The composite birefringent member satisfies a requirement that the second birefringent layer is formed of a polymer such as polyamide and/or a requirement that Δnd and Rth of the composite birefringent member satisfy formulae (I) and (II) below. As a result, the composite birefringent member allows a liquid crystal display to achieve a wide viewing angle, compensates birefringence of a liquid crystal cell, and does not cause display coloring of the liquid crystal display. Δnd400/Δnd550 1 (II)
