METHOD FOR MANUFACTURING THREE LAYER ACCUMULATION OF OPTICAL FILMS

摘要

PURPOSE: A method for manufacturing a three layer accumulation of optical films is provided to omit a step of cutting chips in order to cut the three layer accumulation of optical films with a single step process. CONSTITUTION: In a method for manufacturing a three layer accumulation of optical films, a rectangular(ABCD) two layer accumulation of optical films(40) is cut along with a reference line(EF). The first two layer accumulation(41) of optical films and second two layer accumulation(42) of optical films are accumulated on a third optical film(32) having an optical axis(31) in parallel or normal direction to the first and second two layer accumulation of optical films. Then, the attained band-like three layer accumulation of optical films(52) is cut along with the region(70) on which the one of the first or second two layer accumulation of optical films and the third optical films overlaps.
