发明名称 OPTICALLY COMPENSATED ACRYLIC PRESSURE-SENSITIVE ADHESIVE COMPOSITION, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE CONTAINING THE SAME
摘要 The present invention relates to an acrylic pressure-sensitive adhesive composition which comprises a (meth)acrylic copolymer comprising 70 to 95 parts by weight of an alkyl(meth)acrylic acid ester monomer, in which alkyl has 2 to 14 carbon atoms, and 5 to 30 parts by weight of a (meth)acrylic acid ester monomer containing a copolymerizable aromatic group, wherein the composition has a gel fraction of 10 to 55% and a swelling ratio of 30 to 110, and a sol (uncross-linked polymer) eluted therein with a solvent has a weight average molecular weight of 600,000 or more; a polarizing plate comprising the composition; and a liquid crystal display device comprising the same. The composition according to the present invention provides workability such as an excellent durability and re-workability, and has an effect of improving a light leakage phenomenon, since the size of birefringence occurred under stress is very small.
