Provided is an adhesive layer having a first face and a second face which is on the reverse side from the first face, wherein an adhesive composition containing a base polymer forms the base of the entire adhesive layer, the first face has a first refractive index based on the adhesive composition, and the second face has a second refractive index lower than the first refractive index of the first face. This adhesive layer is capable of effectively suppressing internal reflection and has good adhesion even when applied to an optical member having a low refractive index, such as an antireflection film, a light diffusion film, a prism film, a light guide film, a lens film, or a Fresnel lens, lenticular lens, or microlens film. |
