Abstract

Un film optique multicouche (X) selon la présente invention est pourvu de manière séquentielle d'un film optique (10), d'une couche adhésive (30) et d'un film optique (20) dans la direction de l'épaisseur (H). La couche adhésive (30) est liée au film optique (10), tout en étant également liée au film optique (20). La couche adhésive (30) a une partie d'extrémité étendue (30a). La partie d'extrémité étendue (30a) s'étend vers l'extérieur au-delà d'un bord (11) du film optique (10) et d'un bord (21) du film optique (20) dans une direction plane qui est perpendiculaire à la direction d'épaisseur (H).
