PROBLEM TO BE SOLVED: To provide a polarizing plate with an adhesive layer which has the excellent durability and which does not make a display panel warp easily and does not cause thermal unevenness easily, even if the polarizing plate is a thin film.SOLUTION: A polarizing plate 10 with an adhesive layer includes a polarizer 21, a first protection layer 22 stacked on one side of the polarizer, a second protection layer 23 stacked on the other side of the polarizer, and an adhesive layer 1 stacked on a surface of the second protection layer opposite to a surface thereof on the polarizer side. The adhesive layer is formed of an adhesive including an adhesive composition containing: a (meth)acrylic acid ester copolymer containing a monomer including an alicyclic structure, a monomer including an aromatic ring, and a monomer including a hydroxyl group as the monomer unit of the polymer and having a hydroxyl value of 5 to 20 mgKOH/g, an acid value of 5 mgKOH/g or less, and a weight-average molecular weight of 1,300,000 to 3,000,000; and an isocyanate crosslinking agent. The adhesive has a gel fraction of 60 to 89%.SELECTED DRAWING: Figure 1 |
