Claim:
1. 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 liquid crystal cell, the front-plate-integrated polarizing plate including a front-side polarizing plate and a front plate, the front plate being disposed at a viewing side of the front-side polarizing plate and having a Young's modulus equal to or greater than 2 GPa, the back-side polarizing plate having an amount of shrinkage Y of 0.5 mm or less in an absorption axis direction when stuck to a glass substrate and heated at 85° C. for 500 hours, the front-side polarizing plate having an amount of shrinkage X in an absorption axis direction when stuck to a glass substrate and heated at 85° C. for 500 hours, the amount of shrinkage X being smaller than the amount of shrinkage Y, the front-side polarizing plate and the back-side polarizing plate each comprising a pressure sensitive adhesive layer for sticking to the liquid crystal cell, and the pressure sensitive adhesive layer of the front-side polarizing plate and the pressure sensitive adhesive layer of the back-side polarizing plate having a thickness of 5 to 50 μm.
