Abstract:
1. A polarizing plate, comprising: a) a polyvinyl alcohol polarizer and b) a hardening resin layer which is provided on at least one side of the polyvinyl alcohol polarizer and formed from a photocurable composition comprising: 4 to 95 parts by weight of (A) a photocurable acrylic polymer, 4 to 95 parts by weight of (B) a poly-functional acrylic monomer, and 1 to 20 parts by weight of (C) a photo-polymerization initiator, based on 100 parts by weight of the photocurable composition, wherein (A) the photocurable acrylic polymer comprises (a) an acrylate-based monomer, (b) an aromatic vinyl-based monomer, (c) an N-substituted maleimide-based monomer, and an acryloyl functional group, wherein (A) the photocurable acrylic polymer comprises 30 to 98 parts by weight of (a) the acrylate-based monomer based on 100 parts by weight of (A) the photocurable acrylic polymer, wherein (A) the photocurable acrylic polymer comprises 1 to 30 parts by weight of (b) the aromatic vinyl-based monomer based on 100 parts by weight of (A) the photocurable acrylic polymer, and wherein (A) the photocurable acrylic polymer comprises 1 to 40 parts by weight of (c) the N-substituted maleimide-based monomer based on 100 parts by weight of (A) the photocurable acrylic polymer.
