Abstract
The present invention relates to an acrylic pressure-sensitive adhesive composition, a polarizing plate and a liquid crystal display device, using the same. More specifically, the present invention relates to an acrylic pressure-sensitive adhesive composition having optimal stress releasing property which comprises an optically compensated acrylic copolymer (A) containing a cross-linkable functional group, an optically compensated acrylic copolymer (B) containing no cross-linkable functional group, and a multi-functional cross-linking agent (C). A polarizing plate and a liquid crystal display device comprising the pressure-sensitive adhesive composition meets with major properties such as adhesion endurance reliability, with effectively providing optical compensation effect and stress release effect, and has an effect of improving a light leakage phenomenon.
