| titleOfInvention | Method of Providing Optical Compensation Film, Optical Compensation Film, Circular Polarizing Plate and Liquid Crystal Display |
| abstract | A method of making an optical compensation film, comprising stretching a cellulose acetate having a water content of 2.0 to 20.0 weight percent, the method comprising: a cellulose acetate for the film having an acetyl value of 57.0 to 62.5%; An optical compensation film prepared according to a method for producing an optical compensation film; A polarizing plate, which is a laminate comprising an optical compensation film and a polarizing film; And an image display containing at least one of an optical compensation film and a polarizing plate. According to the method for producing the optical compensation film of the present invention, the optical scale of the optical compensation film having a large NZ factor and good visual characteristics (particularly λ / 4 plate having a retardation difference of λ / 4 in a wide wavelength range) It can be manufactured stably. In particular, in the method, the NZ factor of the optical compensation film to be produced can be well adjusted without changing its delay, so that the method ensures stable industrial scale production of the optical compensation film with improved visual characteristics. Let's do it.n n n Furthermore, image displays containing optical compensation films made according to the method of the invention or containing polarizing plates with optical compensation films, in particular image displays with reflective or semi-transmissive liquid crystal displays and organic electroluminescent devices are all good visual features.
