<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminate and a method for manufacturing a retardation plate with high positioning accuracy, and to provide a retardation plate for enhancing positioning accuracy. <P>SOLUTION: A film having a retardation between (n/2-0.14)λ or more to (n/2+0.14)λ or less is used as a protection film 13 for protecting a retardation layer 12. In the process of manufacturing, when a retardation plate 10 is punched out from a retardation roll sheet 10D, a retardation plate 440 constituted by a retardation plate having a retardation of (2n+1)λ/4 and a polarizing plate 450 are disposed between a camera 410 and the retardation roll sheet 10D. <P>COPYRIGHT: (C)2012,JPO&INPIT |
