发明名称 CELLULOSE ESTER FILMS, POLARIZING PLATES AND LIQUID CRYSTAL DISPLAYS EQUIPPED THEREWITH
摘要 [Object] To provide cellulose ester films having high transmittance, and polarizing plates with less deterioration at the time when durability is tested and liquid crystal displays having high contrast, both of which comprise such cellulose ester films. [Means for Solving the Problems] Cellulose ester films comprising 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; and 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 degree of substitution is 2.8 to 6.0; and further the cellulose ester film having a film thickness of 10 to 35 mum; and polarizing plates and liquid crystal displays equipped therewith.
