Abstract
(EN)
Provided is a means for dealing with further thinned image processing devices. In this laminate for circular polarization element transfer, a polarizer and a λ/4 retardation layer are laminated in this order on a releasable film, or a λ/4 retardation layer and a polarizer are laminated in this order on the releasable film. It is possible to manufacture an image display device having a circular polarization element by transferring the laminate to a constituent member of the image display device.

L'invention concerne un moyen permettant de traiter des dispositifs de traitement d'images réduites davantage. Dans ce stratifié pour un transfert d'élément de polarisation circulaire, un polariseur et une couche de retard λ/4 sont stratifiés dans cet ordre sur un film libérable, ou une couche de retard λ/4 et un polariseur sont stratifiés dans cet ordre sur le film libérable. Il est possible de fabriquer un dispositif d'affichage d'image ayant un élément de polarisation circulaire en transférant le stratifié à un élément constitutif du dispositif d'affichage d'image.
