  • Publication number: 20140153095
    Abstract: Provided is a polarizing plate having pressure-sensitive adhesive layer, including a polarizer, a transparent protective film placed on at least one surface of the polarizer, and a pressure-sensitive adhesive layer placed on a surface of the transparent protective film on a side where the polarizer is not placed. The pressure-sensitive adhesive layer is formed from pressure-sensitive adhesive including acryl-based polymer including alkyl (meth)acrylate monomer unit and aromatic ring structure-containing (meth)acrylate monomer unit. The transparent protective film has an absolute value of photoelastic coefficient of 50×10?12 (m2/N) or less, and X and Y satisfy the relation ?1×1011X+3?Y??1×1011X+23. X represents the photoelastic coefficient (m2/N) of the transparent protective film, and Y represents the content (%) of the aromatic ring structure-containing (meth)acrylate monomer unit in the acryl-based polymer.
