An object of the invention is to provide a pressure-sensitive adhesive optical film-peeling method capable of easily detaching the pressure-sensitive adhesive optical film from a glass substrate with no damage to the glass substrate or no adhesive deposit on the glass substrate, and to provide a pressure-sensitive adhesive optical film suitable for use in such a peeling method. The invention is directed to a method for peeling a pressure-sensitive adhesive optical film from an optical film-carrying glass substrate including a glass substrate and the pressure-sensitive adhesive optical film bonded thereto, which includes: exposing the optical film-carrying glass substrate to an environment at a temperature of 40 to 98° C. and a relative humidity of 60 to 99% for three minutes or more; and then peeling the pressure-sensitive adhesive optical film from the glass substrate under the environment.

Provided is a pressure-sensitive adhesive composition capable of realizing a pressure-sensitive adhesive layer having satisfactory adhesion performance and a low dielectric constant. This pressure-sensitive adhesive composition is characterized by containing a methacrylic polymer with a glass transition temperature (Tg) of 0° C. or less obtained by polymerization of monomer components including 40-99.5 weight % of alkyl methacrylate having a C10-C18 alkyl group in a side chain. A pressure-sensitive adhesive layer and an adhesive sheet are also prepared from the said pressure-sensitive adhesive composition.

Disclosed is an optical sheet with an adhesive layer, which has excellent adhesion, excellent aggregability and excellent long-term durability, and wherein an adhesive layer part does not fill recesses and projections over time, said recesses and projections having been formed by processing. Specifically, an optical sheet with an adhesive layer is produced by arranging an adhesive layer on a recessed and projected surface of an optical film which has been subjected to processing for forming recesses and projections. In addition, the optical sheet with an adhesive layer is bonded to various light sources or image display elements, thereby obtaining light sources or image display devices that have improved light extraction efficiency without changing the designs of the light sources or image display elements, while securing uniform light emission and improving viewing angles especially in devices that comprises the image display elements.
