Abstract:
Provided is a set of polarizing plates comprising a front-plate-integrated polarizing plate to be disposed at a viewing side of a liquid crystal cell and a back-side polarizing plate to be disposed at a back-side of the cell. The front-plate-integrated polarizing plate includes a front-side polarizing plate and a front plate having a Young's modulus of 2 GPa or more. An amount of shrinkage observed in the front-side polarizing plate in an absorption axis direction after the front-side polarizing plate is stuck to a glass substrate and heated at 85° C. for 500 hours is taken as X, and an amount of shrinkage observed in the back-side polarizing plate in an absorption axis direction after the back-side polarizing plate is stuck to a glass substrate and heated at 85° C. for 500 hours is taken as Y, the amount of shrinkage X being smaller than the amount of shrinkage Y.
