Title (EN) DEPOLARIZATION ELEMENT
(FR) ÉLÉMENT DE DÉPOLARISATION
(JA) 偏光解消素子
Abstract:
(EN) The purpose of the present invention is to provide a depolarization element capable of minimizing color changes brought about by transmission while maintaining high transparency and of suppressing an increase in thickness of the element. The depolarization element includes a liquid crystal layer comprising a liquid crystal wherein a plurality of regions having mutually different thicknesses are arranged.
(FR) L'objectif de la présente invention est de fournir un élément de dépolarisation capable de minimiser les changements de couleur provoqués par la transmission tout en conservant une transparence élevée et de supprimer une augmentation de l'épaisseur de l'élément. L'élément de dépolarisation comprend une couche de cristaux liquides comprenant un cristal liquide, où une pluralité de régions ayant des épaisseurs mutuellement différentes sont agencées.
(JA) 透明性を高く維持しつつ、透過による色味の変化を少なくすることができるとともに、厚くなることを抑えることが可能な偏光解消素子を提供することを目的とし、厚さが異なる複数の領域が配列された液晶からなる液晶層を有するものとする。
