| titleOfInvention | Method for producing optical compensating film, optical compensating film, circularly polarizing plate, and liquid crystal display |
| abstract | Provided are a method for producing an optical compensating film, which comprises stretching a cellulose acetate film, the cellulose acetate film having a water content of 2.0 to 20.0 % by weight, wherein the cellulose acetate for the film has an acetyl value of from 57.0 % to 62.5 %; the optical compensating film produced according to the method for producing an optical compensating film; a polarizing plate that is laminate including the optical compensating film and a polarizing film; and an image display that comprises at least one of the optical compensating film and the polarizing plate. According to the method for producing an optical compensating film of the invention, optical compensating films having a large NZ factor and having good view angle characteristics (especially λ/4 plates having a phase difference of λ/4 in a broad wavelength range), can be stably produced on an industrial scale. In particular, in the method, the NZ factor of the optical compensating films produced can be well controlled, without changing the retardation thereof, and therefore the method ensures industrial-scale stable production of optical compensating films having improved view angle characteristics. In addition, image displays, especially reflection or semi-transmission liquid crystal displays and organic electroluminescent device-having image displays that comprise the optical compensating film produced according to the method of the invention or comprise a polarizing plate having the optical compensating film all have good view angle characteristics. |
