METHOD FOR MANUFACTURING MACHINED OPTICAL LAMINATE WITH ATTACHED ADHESIVE LAYER

The present invention provides a method which enables easy and low-cost manufacture of a machined optical laminate with an attached adhesive layer, whereby separation defects in a surface protection film are minimized and tapering of the machined surface is minimized. This method for manufacturing a machined optical laminate with an attached adhesive layer involves: forming a workpiece by layering a plurality of sheets of the optical laminate with an attached adhesive layer; machining the outer peripheral surface of the workpiece using an end mill having a helical cutting edge; and further machining the outer peripheral surface of the machined workpiece using an end mill with a 0-degree edge angle. The optical laminate with an attached adhesive layer comprises an optical film, an adhesive layer disposed on one side of the optical film, a separator temporarily attached to the adhesive layer in a separable manner, and a surface protection film temporarily attached to the other side of the optical film in a sepa
