发明名称 POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE
摘要 A polarizing plate (3) in which the total thickness of a first protective film (11) and a polarizing film (12) is 50 μm or less. A second protective film (13) contains a cellulose ester and a retardation-lowering agent. The retardation-lowering agent contains a sugar ester obtained by esterifying, with an aliphatic acyl group, all or some of OH groups in a compound (A) having at least one furanose or pyranose structure or in a compound (B) in which two to twelve furanose structures and/or pyranose structures are bonded. The sugar ester is contained at a proportion of at least 70% of the total mass of the retardation-lowering agent. In the second protective film (13), Ro is 0 to 10 nm and Rt is -10 to +10 nm.
