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, the peeling failure of a surface protective film of the optical laminate is inhibited, and the cutting surface is inhibited from becoming a tapered shape. 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; cutting the outer peripheral surface of the workpiece by using an end mill with a spiral blade; and further cutting the outer peripheral surface of the cut workpiece using an end mill having an edge angle of 0 DEG. 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 ma
