Zusammenfassung:	Provided is a laser cutting and machining method for a polarizing optically functional film laminate including, as a minimum constituent element, a polarizing film having a protective film laminated upon at least one side of a polarizer. This cutting and machining method laser cuts and machines a polarizing optically functional film laminate having at least a polarizing film having a protective film laminated on at least one side of a polarizer. The method cuts the polarizing optically functional film laminate into a prescribed shape by performing laser cutting whereby: a sheet material is stacked and arranged on one surface of the polarizing optically functional film laminate, said sheet being separate from the polarizing optically functional film laminate; laser light is irradiated in the thickness direction of the polarizing optically functional film laminate, from the other surface of the polarizing optically functional film laminate, said surface being positioned on the opposite side to the sheet materia
