Provided is a pressure-sensitive adhesive for an optically functional film which can carry out adhesion with a good durability in adhesion of an optically functional film such as adhesion of a polarizing plate, particularly a polarizing plate integrated with a viewing angle expanding film and the like with a liquid crystal cell, adhesion of a polarizing plate with a retardation film, adhesion of a retardation film with a retardation film and adhesion of a retardation film with a liquid crystal cell and which has the characteristics that a liquid crystal display obtained therefrom is less liable to cause light leakage even under the environment of high temperature and high humidity and that static electricity is less liable to be produced when peeling off a release film from a pressure-sensitive adhesive layer. The pressure-sensitive adhesive for applying an optically functional film comprises a pressure-sensitive adhesive resin and an antistatic agent, wherein a storage elastic modulus (G′) at 23° C. is 0.3 MPa or more, and a charged voltage on the surface of a layer comprising the above pressure-sensitive adhesive which is measured 5 seconds later since peeling off a release film brought into contact with the above pressure-sensitive adhesive layer under the environment of 23° C. and a relative humidity of 50% is 1.0 kV or less.
