<p>PROBLEM TO BE SOLVED: To provide a production method of a laminate optical film comprising a release film, an adhesive layer, an optical film and a surface protective film, layered in this order, by which the surface protective film can be inhibited from peeling from the optical film on a cut surface when the laminate is cut.SOLUTION: The production method of a laminate optical film includes a step of cutting a laminate comprising a release film, an adhesive layer, an optical film and a surface protective film, layered in this order, while leaving the release film. The cutting step is carried out by moving a rotating cutting blade, in which the rotation direction of the rotating cutting blade is in the same direction as the moving direction of the cutting blade, and a ratio (B/A×100) of the rotational speed B to the moving speed A of the rotating cutting blade is 90% or more.</p> |
