[Problem] To provide a polarizing plate adhesive composition which can suppress warping (bending) of liquid crystal cells and which can form an adhesive layer with excellent durability. [Solution] This adhesive composition for a polarizing plate contains (A) a (meth)acrylic copolymer obtained by copolymerizing, in the presence of a multi-functional chain transfer agent, a (meth)acrylate alkyl ester with 4-18 carbons in an alkyl group and a monomer component containing a hydroxy group-containing monomer, (B1) an isocyanate compound, and (B2) a metal chelate compound, and is characterized in that the loss tangent (tanδ1) at 23°C of an adhesive layer formed from the aforementioned composition is 0.33-0.55, and the loss tangent (tanδ2) at 80°C is 0.40-0.65. |
