<p>An optical-use adhesive film comprises a base film of the optical-use adhesive film is a biaxially oriented polyester film having a thickness equal to or more than 50 mum, and an adhesive polymer layer laminated on at least one surface of the base film. Refractive indexes of the base film in longitudinal and transverse directions are both in the range of from 1.55 to 1.70 and refractive indexes of the adhesive layer and the base film satisfies the following formula (1):wherein Nx and Ny respectively indicate refractive indexes in longitudinal and transverse directions of a base film and Nc is a refractive index of an adhesive layer.</p> |
