摘要： The present invention provides a fabrication method which promotes adhesion of sheet materials when bonding a plurality of optical sheets into a compound sheet and provides a manufacturing method of optical sheets suitable for liquid crystal display units and the like. A manufacturing method according to one aspect of the present invention includes a lamination step of laminating a plurality of optical sheets; and a bonding step of irradiating at least one or more spots on a laminate of the optical sheets prepared in the lamination step with a laser beam from one side of the laminate and thereby bonding the irradiated spots to obtain a compound optical sheet in which the plurality of optical sheets are integrated. Preferably, the method further includes a step of forming a photothermal conversion layer from a light absorber between the optical sheets to be fused. Incidentally, ultrasonic welding may be used instead of, or in combination with, laser welding.
摘要翻译：本发明提供了一种制造方法，其在将多张光学片粘合到复合片中时促进片材的粘附，并提供适合于液晶显示单元等的光学片的制造方法。根据本发明的一个方面的制造方法包括层压多个光学片的层压步骤; 以及将在层压工序中制备的光学片的层压体上的至少一个以上的点照射到来自层叠体的一侧的激光的粘合工序，从而将照射光斑接合，得到复合光学片，其中多个的光学片被集成。优选地，该方法还包括从要融合的光学片之间的光吸收剂形成光热转换层的步骤。顺便提及，可以使用超声波焊接来代替激光焊接或与激光焊接结合使用。

摘要： In a manufacturing method of the present invention, a diffusion sheet having a flat size of a product size or more is laminated to a front surface and/or back surface of a lens sheet having flat size of the product size or more, and the stack is cut along its periphery into the product size, and the lens sheet and the diffusion sheet are bonded to each other at at least one or more peripheral points thereof. This eliminates a step for individually cutting a number of films (sheets) into a product size, and a step for aligning the number of films (sheets) for lamination. In addition, the method does not cause a problem of waste of protective sheets, but provides advantages in both cost and quality. There is no problem caused in laminating a number of films, or problems caused by different thermal expansions/thermal shrinkages of a plurality of films.
摘要翻译：在本发明的制造方法中，将具有产品尺寸以上的平面尺寸的漫射片层叠到具有产品尺寸以上的平坦尺寸的透镜片的前表面和/或后表面，并且叠层沿着其周边切割成产品尺寸，并且透镜片和漫射片在至少一个或多个外围点处彼此接合。这消除了将多个膜（片）单独切割成产品尺寸的步骤，以及用于对齐用于层压的膜（片）数量的步骤。另外，该方法不会造成保护片的浪费的问题，而且在成本和质量两方面均具有优点。在层叠多个薄膜方面没有问题，或者由多个薄膜的不同的热膨胀/热收缩引起的问题。
