Cellulose ester film, polarizing plate, liquid crystal display and process for producing cellulose ester film |
摘要 |
A cellulose ester film has a front retardation Re of from 20 nm to 100 nm relative to light having a wavelength of 590 nm at 25° C. and 60% RH; a retardation Rth in a film thickness direction of from 60 nm to 400 nm relative to light having a wavelength of 590 nm at 25° C. and 60% RH; and a shrinkage factor in a slow axis direction of less than 1% in the range of from a glass transition temperature to a temperature of 40° C. higher than a glass transition temperature. |
