Abstract: An end face of a polarization plate cut by laser becomes a substantially flat surface having only sloping micro waviness because of having been melted once to be solidified. Since the surface has few stress-concentrated parts that may cause microcracks, this prevents microcracks from easily being produced.

Abstract: A strip-shaped polarizing film has a protective film strip conformably adhered to one surface thereof and a releasable liner conformably adhered to the other surface thereof and delivered from a film delivering station 1. After an appearance inspection, a lamination of the protective film strip and the polarizing film strip F is half-cut using a laser unit 11 to form an array of laminations each consisting of a protective film and a polarizing film F, with the releasable liner being left intact. Then, the polarizing films F are fed to a peeling mechanism 4. The peeling mechanism 4 feeds a forwardmost one the polarizing films F to a laminating mechanism 5 while peeling off the releasable liner therefrom by a knife-edged member. The forwardmost polarizing film F is laminated to a liquid-crystal panel W conveyed to the laminating mechanism by a panel transport apparatus 18 in synchronization of the feeding of the forwardmost polarizing film F.

Abstract: This invention relates to an optical film cutting method which includes cutting an optical film by irradiating the optical film with a laser beam under conditions that an energy per unit length is 0.12 to 0.167 J/mm and that a continuous irradiation time is 0.1 msec or less; as well as to an optical film that is cut by the cutting method and has a size of a raised part generated on a cutting surface thereof of 30 ?m or less.

Abstract: A first through hole is formed in a laminate by trepanning machining using laser light, for example. The trepanning machining refers to a process for irradiating laser light along such a trajectory that the laser light is first irradiated onto a substantially central area of a first through hole to be formed, the laser light is irradiated along a circumference corresponding to the bore diameter of the first through hole to be formed, and the laser light is finally irradiated onto the substantially central area of the first through hole to be formed again. A second through hole being substantially concentric with and having a larger bore diameter than the first through hole is formed by irradiating the laser light, similarly to the first through hole.
