This adhesive optical film has an optical film, and an adhesive agent layer which is provided on the optical film; the adhesive agent layer has a thickness (µm) standard deviation of not more than 0.12µm. The adhesive optical film can reduce the problem of irregularity in visibility due to an adhesive agent layer. L'invention porte sur un film optique adhésif comprenant un film optique et une couche d'agent adhésif déposée sur le film optique, la couche d'agent adhésif possédant un écart type d'épaisseur (µm) inférieur à 0,12 µm. Le film optique adhésif selon l'invention permet d'atténuer les irrégularités dans la visibilité dues à la couche d'agent adhésif.
