METHOD FOR MANUFACTURING POLARIZING PLATE |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a polarizing plate which is capable of uniformly pressurizing a laminate (a polarizing film and a transparent film) constituting a polarizing plate even if using sticking rolls of which the diameter is relatively smaller, and an apparatus for manufacturing a polarizing plate. <P>SOLUTION: A method for manufacturing a polarizing plate includes: an adhesive coating process for applying an active energy ray curable adhesive to one surface of a transparent film or to one surface or both surfaces of a polarizing film; a sticking process for sticking the transparent film and the polarizing film by pressing at least one of a pair of sticking rolls toward a direction of the other sticking roll by using at least one pressing roll provided in contact with the sticking rolls in a state where a laminate formed by laminating the transparent film on one surface or both surfaces of the polarizing film via the adhesive is interposed between the pair of sticking rolls rotating in a conveyance direction; and an active energy ray irradiation process for curing the adhesive by irradiating the laminate with the active energy ray. A diameter of the center part of the pressing roll is larger than a diameter of the center part of the sticking rolls in contact with the pressing roll. <P>COPYRIGHT: (C)2013,JPO&INPIT |
