Kind Code:
A1
Abstract:
Provided is a simple method for manufacturing an adhesive-layer-attached optical laminate that prevents floating of a release liner. A method for manufacturing an adhesive-layer-attached optical laminate according to an embodiment of the present invention includes: forming a workpiece by stacking a plurality of sheets of adhesive-layer-attached optical laminate and a plurality of sheets of interposed film alternately; and cutting an outer peripheral surface of the workpiece. In one embodiment, the adhesive-layer-attached optical laminate includes: an optical film; a first adhesive layer with a thickness of 50 μm or more disposed on one side of the optical film; a first release liner temporarily attached to the first adhesive layer so as to be releasable; a second adhesive layer disposed on another side of the optical film; and a second release liner temporarily attached to the second adhesive layer so as to be releasable.
