Abstract: A pressure-sensitive adhesive containing a pressure-sensitive adhesive resin and fine particles having an average particle diameter of 0.1 to 20 ?m. The pressure-sensitive adhesive has a storage elastic modulus (G?) at 23° C. of 0.3 to 15 MPa, and a haze value that is 5% or more.

Abstract: Provided are a pressure-sensitive adhesive for applying an optically functional film by which adhesion can be carried out with good durability in adhesion of a polarizing plate, particularly a polarizing plate integrated with a viewing angle expanding film 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 endows a liquid crystal display with even brightness without bringing about bubbles in a pressure-sensitive adhesive layer and an uneven luminance even after the passage of time, an optically functional film and a production process for the same. The above pressure-sensitive adhesive for applying an optically functional film comprises a pressure-sensitive adhesive resin and fine particles having an average particle diameter of 0.1 to 20 ?m, wherein a storage elastic modulus (G?) at 23° C. is 0.3 to 15 MPa, and a haze value is 5% or more.
