Abstract: An input display device includes a liquid crystal layer containing liquid crystal molecules that are homogeneously aligned in an absence of an electric field, a first polarizer disposed on a viewing side of the liquid crystal layer, a capacitive sensor disposed between the first polarizer and the liquid crystal layer, and an antistatic layer disposed between the first polarizer and the capacitive sensor, the antistatic layer being attached to the first polarizer. The capacitive sensor has a transparent substrate, a transparent electrode pattern formed on the transparent substrate, and a first adhesive layer formed on the transparent substrate to embed the transparent electrode pattern, and the antistatic layer has a surface resistance value of 1.0×109 to 1.0×1011Ω/□.

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.
