Abstract
An adhesive film for polarizing plates includes a (meth)acrylic copolymer obtained by polymerizing about 15 wt % to about 30 wt % of a (meth)acrylic monomer having a hetero-alicyclic ring. The adhesive film has a storage modulus (G′) of about 30 kPa or greater as determined from Frequency sweep testing at 85° C. by oscillation at an angular speed of 10−3 rad/s to 102 rad/s. An adhesive composition for the same, a polarizing plate including the same, and an optical display device including the same are also disclosed.
