ACRYLIC PRESSURE-SENSITIVE ADHESIVE COMPOSITION COMPRISING OPTICALLY ANISOTROPIC COMPOUND, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE COMPRISING THE SAME

摘要

An acrylic pressure-sensitive adhesive composition is provided to effectively control a birefringence property generated by contraction stress and to improve light-leaking phenomenon of a polarizing plate. An acrylic pressure-sensitive adhesive composition comprises an acrylic copolymer; and an optically anisotropic compound having at least one substituent containing an alkyl group, alkenyl group or alkynyl group at a meta position of mesogen. The acrylic copolymer is such that 90-99.9 parts by weight of (meth)acrylic acid ester monomer having carbon number 1-14 and 0.1-10 parts by weight of a crosslinkable group-containing monomer are copolymerized.
