Abstract
It is an object of the present invention to provide a polarizing plate which can suppress display unevenness even when being incorporated into a liquid crystal display device, has neutral hue, and can maintain cross property even when a low water-vapor permeable protective film is used. It is another object of the present invention to provide a method for manufacturing the same. The polarizing plate includes: a polarizing film; an adhesive layer; and a protective film provided on at least one surface of the polarizing film with the adhesive layer interposed therebetween. A ratio (I285/I480) of absorbance I285 of the polarizing film at 285 nm to absorbance I480 thereof at 480 nm is 1.2 or less. The polarizing plate has a hue b value of 4 or less. The protective film has a water-vapor permeability of 100 g/m2·day or less.
