Stretched cellulose ester film, hard coat film, antireflective film, and optical compensation film, and polarizing plate, and display device using them

摘要

In a stretched cellulose ester film containing a plasticizer, the plasticizer includes at least an aromatic terminal ester type plasticizer expressed by the following general formula (1): and stretched cellulose ester film includes a cellulose ester having a total acyl substitution degree of 2.4 to 2.9, a number average molecular weight (Mn) of 30000 to 200000, and a value of a weight-average molecular weight (Mw)/a number average molecular weight (Mn) being 1.4 to 3.0, <?in-line-formulae description="In-line Formulae" end="lead"?>B-(G-A)n-G-B General formula (1) <?in-line-formulae description="In-line Formulae" end="tail"?> where B represents a benzenemonocarboxylic acid residue, G represents an alkylene glycol residue having a carbon number of 2 through 12 or an oxyalkylene glycol residue having a carbon number of 4 through 12, A represents an alkylene dicarboxylic acid residue having a carbon number of 4 to 12, and n indicates an integer of 0 or more.
