Method for manufacturing cut optical laminate with adhesive layer

The invention provides a method for simply and inexpensively manufacturing a cut optical laminate with an adhesive layer, wherein the peeling failure of a surface protective film of the optical laminate is suppressed. The method for manufacturing a cut optical laminate with an adhesive layer according to the present invention comprises the steps of: forming a workpiece by overlapping a plurality of optical laminates with adhesive layers; and cutting the outer peripheral surface of the workpiece using an end mill having a helical edge. The optical laminate with an adhesive layer includes an optical film, an adhesive layer disposed on one side of the optical film, a separator temporarily bonded to the adhesive layer in a peelable manner, and a surface protective film temporarily bonded to the other side of the optical film in a peelable manner. In the manufacturing method of the present invention, an optical laminate with an adhesive layer is stacked to form a workpiece so that a separator is positioned in the
