Adhesive composition for polarizing plate, polarizing plate having adhesive layer, and automotive display

Provided are an adhesive composition for a polarizing plate, a polarizing plate having an adhesive layer, and an automotive display having the polarizing plate, the adhesive composition comprising a (meth)acrylic copolymer and a toluene diisocyanate cross-linking agent, the (meth)acrylic copolymer comprising: a structural unit derived from a (meth)acrylic alkyl ester; and at least one structural unit selected from the group consisting of a structural unit derived from a monomer having a hydroxy group and a structural unit derived from a monomer having a carboxy group, a total content of the structural unit derived from a monomer having a hydroxy group and the structural unit derived from a monomer having a carboxy group with respect all structural units of the (meth)acrylic copolymer being from greater than 0% by mass to 0.45% by mass, and a ratio of a number of moles of an isocyanate group in the toluene diisocyanate cross-linking agent with respect to a total number of moles of the hydroxy group and the car
