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.
