<p>An adhesive composition for a polarizing plate of the present invention includes a specific (meth) acrylic polymer (A), an ionic liquid (B) and an isocyanate-based crosslinking agent (C) each in a specific amount. When an adhesive layer obtained from the adhesive composition for a polarizing plate is provided on a surface of a polarizing plate, the adhesive layer is appropriately plasticized and has improved compatibility with an adherend. Thus, the adhesive layer can eliminate the problems of separation or lifting due to the deflection by the own weight of the polarizing plate, which is significant when a large polarizing plate is laminated to a liquid crystal cell. Furthermore, the adhesive layer can follow fine unevenness on a surface of glass that is a liquid crystal cell substrate, and thus can reliably prevent the separation or lifting of the polarizing plate from the liquid crystal cell even at a high temperature or under a hot and humid environment. The adhesive layer provides excellent adhesion to the liquid crystal cell.</p> |
