| titleOfInvention |
Optical film, polarizing plate and display device utilising the film, and production method of optical film |
| abstract |
An optical film is disclosed having minimal curl, minimal coating unevenness and no cracks. The optical film is obtained by casting a dope comprising a cellulose ester and a non-chlorinated solvent on a metal support, the cellulose ester having a total acyl substitution degree of 2.6 to 2.85 and having a ratio of a weight-average molecular weight to a number-average molecular weight of 1:1 to 3:1; drying the cast dope on the metal support so as to obtain a cellulose ester film; peeling the cellulose ester film from the metal support; further drying the cellulose ester film while providing a longitudinal stretch or a lateral stretch to the cellulose ester film; and providing a metal oxide layer on the cellulose ester film. |
