摘要： Provided are a liquid crystal composition and a method of manufacturing an optical film. The liquid crystal composition which may form a liquid crystal layer having excellent optical characteristics and a high surface hardness may be provided. The liquid crystal layer formed as described above may be used in various applications, and for example, may be disposed on the outermost surface of a display device, such as an LCD or an OLED, or at an outer side of a polarizing layer of the display in which the polarizing layer is disposed at a visible side, thereby serving as a liquid crystal layer which may solve a problem of degrading brightness occurring when an observer watches an image with polarizing sunglasses.

摘要： Provided are an optical film and a display device including the same. The optical film may be disposed at the outermost side of a display device, such as a liquid crystal display or an organic light emitting display, or at an outside of a polarizing layer of the display in which the polarizing layer is disposed at a visible side. The film disposed as described above may overcome degradation of brightness that may occur when an observer watches an image with polarizing sunglasses. The optical film may also have hardness suitable for its use.

摘要： The present application relates to a polarizing plate and a display device including the same. The present application can provide a polarizing plate comprising a retardation layer exhibiting ultraviolet blocking characteristics even in a state where any ultraviolet absorber or light stabilizer is not blended. In addition, the present application can provide a polarizing plate which can be used alone or in combination with an appropriate sunscreen or a light stabilizer as needed to selectively block ultraviolet rays in a region requiring blocking, without affecting display performance, such as color senses and image quality, of a display device, can also be formed thinly without requiring a separate ultraviolet blocking layer, and also has excellent durability, because the polarizing plate exhibits a certain ultraviolet blocking property even in the absence of an ultraviolet absorber or light stabilizer.

摘要： Provided are a liquid crystal device, a composition capable of forming a liquid crystal layer, a method of manufacturing the liquid crystal device, a system for manufacturing the liquid crystal device, and a use of the liquid crystal device. The liquid crystal device is a device capable of exhibiting, for example, a normally white or black mode, which may exhibit a high contrast ratio and be driven with a low driving voltage, and exhibit excellent durability such as thermal stability. Such a liquid crystal device may be applied to various optical modulators such as a smart window, a window protective film, a flexible display device, an active retarder for displaying 3D images, or a viewing angle control film.
