MANUFACTURING METHOD OF OPTICAL SHEETS FOR DISPLAYS |
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. |
