Abstract:
The cellulose ester film contains a cellulose ester(s) having substitution(s) by an acyl group(s) having 3 to 4 carbon atoms, or an acyl group(s) having 2 carbon atoms and an acyl group(s) having 3 to 4 carbon atoms, the cellulose ester having a total degree of substitution with the acyl group(s) of not less than 1.0 and less than 2.0 and sufficing a weight average molecular weight of not more than 150000; a sugar ester compound(s) having not less than one and not more than 12 sugar unit structures, the sugar unit structure being at least one of a pyranose structure or furanose structure, wherein an average percentage of substitution in the sugar unit structure is 35% to 75%; and the cellulose ester film having a film thickness of i0 to 35 μm. The cellulose ester film is used for polarizing plates and liquid crystal displays equipped.
