摘要:
A polarizing plate according to the invention includes a first protective film; a polarizer; a second protective film; and an adhesive layer in this order, in which a moisture vapor permeability of the first protective film is less than or equal to 200 g/m2/24 hours, the second protective film contains cellulose acylate as a major component, a creep amount of the adhesive layer is less than 100 μm, and a shrinkage force of the polarizing plate in an absorption axis direction thereof which is represented by the following expression (A) is lower than or equal to 2000 N/m. Expression (A) is the Shrinkage Force (N/m) of Polarizing Plate in Absorption Axis Direction=Elastic Modulus (GPa) of Polarizing Plate in Absorption Axis Direction×|Humidity Dimensional Change Rate (%) of Polarizing Plate in Absorption Axis Direction|×Thickness (μm) of Polarizing Plate×10.
