Abstract:
1. A method for manufacturing a pressure-sensitive adhesive and retardation layer-attached polarizing plate ( 4 ), comprising: forming a retardation layer-attached polarizing plate ( subjecting the retardation layer-attached polarizing plate ( then laminating an acrylic pressure-sensitive adhesive layer on the retardation layer side of the heat-treated retardation layer-attached polarizing plate ( wherein the iodine-based polarizer ( the polarizing plate ( the retardation layer-attached polarizing plate ( the pressure-sensitive adhesive and retardation layer-attached polarizing plate ( the acrylic pressure-sensitive adhesive layer is formed by a crosslinking reaction of an acrylic pressure-sensitive adhesive comprising a (meth)acrylic polymer (A) and a crosslinking agent, wherein the (meth)acrylic polymer (A) comprises 100 parts by weight of alkyl (meth)acrylate (a1) and 0.01 to 5 parts by weight of a hydroxyl group-containing (meth)acrylic monomer (a2) as copolymerizable components, and the acrylic pressure-sensitive adhesive comprises 0.02 to 2 parts by weight of a peroxide (B) as the crosslinking agent, and 0.001 to 2 parts by weight of an isocyanate compound (C) as the crosslinking agent relative to 100 parts by weight of the (meth)acrylic polymer (A).
