摘要： Provided is an optical film using a cellulose derivative, which is used in image display devices such as liquid-crystal display devices. A liquid-crystal display device with a polarizing plate using the optical film has an excellent viewing angle property. More particularly, the present invention relates to an optical film made of a cellulose ester resin, a portion of hydrogen atoms of hydroxyl groups of which is substituted with two or more substituent groups.

摘要： Provided are an optical compensation film and a method for producing the same. The optical compensation film includes a nematic liquid crystal compound including a compound having at least two mesogens linked to each other with a constant angle, and has hybrid alignment in which the alignment of the liquid crystal compound varies gradually along the thickness direction.
摘要翻译： 提供一种光学补偿膜及其制造方法。 光学补偿膜包括具有至少两个介晶的化合物的向列型液晶化合物，该化合物具有恒定的角度彼此连接，并且具有其中液晶化合物的取向沿着厚度方向逐渐变化的混合取向。
