Claim Text:
1. A polarizer, comprising: a polarization film; and a pressure-sensitive adhesive layer, formed on one side or both sides of the polarization film, comprising a pressure-sensitive adhesive composition which comprises a crosslinkable acrylic copolymer (A) containing a monomer having a crosslinking functional group and a non-crosslinkable acrylic copolymer (B) at a mixture ratio of 1:9 to 3:17, wherein the acrylic copolymer (A) consisting of 75 to 97 parts by weight of a (meth)acrylic acid ester monomer with respect to 100 parts by weight of the acrylic copolymer (A), 3 to 18.3 parts by weight of an aromatic group containing monomer that is benzyl acrylate or phenoxyethyl acrylate with respect to 100 parts by weight of the acrylic copolymer (A), 0.1 to 10 parts by weight of the monomer having a crosslinking functional group with respect to 100 parts by weight of the acrylic copolymer (A), and a polymerization initiator, and the acrylic copolymer (B) consisting of 75 to 97 parts by weight of a (meth)acrylic acid ester monomer with respect to 100 parts by weight of the acrylic copolymer (B), 3 to 18.3 parts by weight of an aromatic group containing monomer that is benzyl acrylate or phenoxyethyl acrylate with respect to 100 parts by weight of the acrylic copolymer (B), and a polymerization initiator, wherein weight average molecular weights of the acrylic copolymers (A) and (B) are more than 1,000,000, respectively.
