Abstract
An adhesive film for polarizing plates has a K value of about 0.2 to about 0.5, as calculated by Equation 1. A polarizing plate includes the adhesive film for polarizing plates. An optical display includes the polarizing plate. The adhesive films for polarizing plates according to embodiments of the invention suppress light leakage due to dimensional changes in the polarizing plates at high temperature and/or high humidity.K=ΔG′×ΔR0 Equation 1
