<p>The purpose of the present invention is to provide a polarizing plate that can mitigate uneven display resulting from changes in temperature and humidity, a method for manufacturing the polarizing plate, and a liquid crystal display device provided with the polarizing plate. This polarizing plate has a protective film containing a cellulose ester disposed on at least one surface of a polarizing element, the polarizing plate being characterized in that a maximum value for tanδis 0.6 or greater when tanδis obtained by measuring the dynamic viscoelasticity of the protective film at a frequency of 1Hz while the temperature is changed within a range of 25-190˚C, and in that E1/E2 is 1.5 to 3.0 where values of elastic moduli (MPa) for an MD direction and a TD direction during production of the protective film are expressed respectively as E1 and E2, which are obtained through measurement at a temperature of 23˚C and a relative humidity of 55%, E1/E2 being a ratio of elastic moduli for the MD direction and the TD direction.</p> |
