| titleOfInvention | Cellulose acylate film and production method thereof, polarizing plate, liquid crystal display device |
| abstract | The present invention relates to a method for producing a cellulose acylate film which is low in production cost, has a large Rth per film thickness of the resulting film, has a low internal haze, and is less likely to cause display unevenness due to changes in humidity when incorporated into a liquid crystal panel as a polarizing plate. Offer. A step of obtaining a film by casting a dope containing cellulose acylate having a total acyl substitution degree of 2.1 to 2.8 and at least one of a polycondensation ester and a sugar ester compound on a support; A step of stretching the film in the film transport direction by 1 to 30% in the state of residual volatile content H1 satisfying the following formula (i), and the film in the film transport direction of residual volatile content H2 satisfying the following formula (ii) A method for producing a cellulose acylate film, wherein the film is stretched in a direction perpendicular to the film conveying direction or the film conveying direction at a temperature T satisfying the following formula (iii). . Formula (i) H1 ≦ 10%; Formula (ii) H2 ≦ 10%; Formula (iii) Tg−15 ° C. ≦ Extension temperature T <Tg + 25 ° C. [Selection figure] None |
