Problems solved by technology
In recent years, as the demand for LCD TVs has increased, LCD TVs have grown in size and brightness, but there has been a problem of subtle optical unevenness
In particular, the OCB type liquid crystal display device, which is excellent in animation adaptability, which is an important factor of television, is expected to pose a big problem of optical unevenness because the display principle is a birefringence type.

Abstract
The present invention provided a method for stably and continuously manufacturing an optical compensating film which has a superior optical compensating function for an OCB type liquid crystal display device and also has small optical unevenness, and to provide the optical compensating film obtained by the method, a polarizer using the same, and a liquid crystal display device. Disclosed are the method for manufacturing the optical compensating film having a stage of forming a liquid crystal compound layer by coating a base with coating liquid containing a polymerizable liquid crystal compound, a stage of forming an optical anisotropic layer by aligning the liquid crystal compound after drying the liquid crystal compound layer and then fixing the alignment, and a stage of further heating the optical anisotropic layer at heating temperature of 40 to 150 DEG C for a heating time of 5 to 3,000 seconds after fixing the alignment of the liquid crystal compound, the optical compensating film obtained by the method, the polarizing plate using the same and the liquid crystal display device.
Description
technical field The present invention relates to an optical compensation film having an optically anisotropic layer in which a polymerizable liquid crystal compound is aligned, a method for producing the same, a polarizing plate and a liquid crystal display device using the optical compensation film. Background technique In recent years, optical films having a layer in which a liquid crystal compound is highly oriented and fixed have been used in various applications such as optical compensation films for liquid crystal display devices, brightness enhancement films, and optical compensation films for projection display devices. The development of optically compensating films for devices has attracted attention. Generally, a liquid crystal display device includes a polarizing plate and a liquid crystal cell. In the currently mainstream TN type TFT liquid crystal display device, an optical compensation film is inserted between the polarizing plate and the liquid crystal cell,...
