Abstract
An adhesive composition for a polarizing plate is adapted to exhibit a variation in relaxation modulus of an adhesive layer in a range of 75% to 95% before and after leaving the same at a temperature of −20° C. to 0° C. for 4 hours, such that it is possible to remarkably improve thermal-shock durability of the polarizing plate, and suppress a damage of the polarizing plate in a thermal-shock durability test, while maintaining excellent adhesiveness.
