摘要:
A substrate for liquid crystal display device comprising, between a substrate and a color filter layer, a positive uniaxial optically anisotropic layer having an optical axis in an in-plane direction of the substrate and a negative uniaxial optically anisotropic layer having an optical axis in a direction perpendicular to the substrate surface, which can provide a vertical alignment (VA)-mode liquid crystal display device with excellent contrast-viewing angle characteristics.
摘要:
A substrate for liquid crystal display device comprising a layer having irregular differences in level and a smoothing layer provided directly on the layer having irregular differences in level, wherein the thickness of the smoothing layer is greater than the irregular differences in level, and the in-plane retardation of the layer inclined of 40° with the retardation axis as the axis of rotation is 5 to 150 nm, which enables to reduce the number of steps in manufacturing, is provided by the present invention.
摘要:
A process of producing a substrate for liquid crystal display device comprising an optically anisotropic layer, which comprises forming the optically anisotropic layer by a process comprising the following [1] to [3]:[1] preparing a substrate having a raw optically anisotropic layer; [2] subjecting the raw optically anisotropic layer to patterned exposures of two or more types having different exposure conditions to each other; [3] subjecting the substrate obtained after the exposure to a heat treatment at 80° C. or higher and 400° C. or lower. By the process, a substrate for liquid crystal display device which contribute to reducing viewing angle dependence of color of a liquid crystal display device can be easily produced.
