PROBLEM TO BE SOLVED: To provide a stretched cellulose acylate film having little planar failure and uniform optical characteristics, and a liquid crystal display device having high display quality by using a polarizing plate with little planar failure for a liquid crystal display device. To provide. A dope containing cellulose acylate and a low molecular weight compound having a molecular weight of 200 or more and 1,000 or less and 2% by weight or more and 15% by weight or less with respect to cellulose acylate is cast, dried, stripped, stretched, and after In the production of a cellulose acylate film to be dried, the production of the cellulose acylate film is characterized in that the volatilization amount from the film of the low molecular compound in the process from casting to the end of post-drying is 300 mg / m 2 or less. A polarizing plate in which a protective film is bonded to both sides of a method and a polarizer, a polarizing plate using the cellulose acylate film as a protective film, a liquid crystal cell, and a liquid crystal display using the polarizing plate. |
