摘要： 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.
