In a stretched cellulose ester film containing a plasticizer, at least one of the plasticizers is an aromatic terminal ester plasticizer represented by the following general formula (I), and the stretched cellulose ester film has a total acyl group. Having a cellulose ester having a degree of substitution of 2.4 to 2.9, a number average molecular weight (Mn) of 80,000 to 200,000, and a weight average molecular weight (Mw)/number average molecular weight (Mn) value of 1.4 to 3.0. A stretched cellulose ester film. General Formula (I) B-(GA)n-GB With the above configuration, the web is less likely to be broken during film formation, and sticking failure or dent failure during transportation is suppressed, and the size is reduced. It is possible to provide a stretched cellulose ester film, a hard coat film, an antireflection film and an optical compensation film which are excellent in stability and flatness, and a polarizing plate and a display device using them. |
