Title (EN) DEPOLARIZING FILM AND METHOD FOR PRODUCING SAME
(FR) FILM DE DÉPOLARISATION ET SON PROCÉDÉ DE PRODUCTION
(JA) 偏光解消フィルム及びその製造方法
Abstract:
(EN) A depolarizing film which is provided with a base film and a depolarizing layer that is formed on at least one surface of the base film and has a function of converting linearly polarized light into partially polarized light or non-polarized light, and wherein: the depolarizing layer contains a liquid crystalline compound or an orientation fixed compound of the liquid crystalline compound; the base film comprises a surface treatment layer into which oxygen atoms are introduced; and the surface treatment layer and the depolarizing layer are in direct contact with each other.
(FR) L'invention concerne un film de dépolarisation qui comprend un film de base et une couche de dépolarisation qui est formée sur au moins une surface du film de base et qui a pour fonction de convertir une lumière à polarisation linéaire en lumière à polarisation partielle ou lumière non polarisée, et dans lequel : la couche de dépolarisation contient un composé cristallin liquide ou un composé d'orientation fixe du composé cristallin liquide ; le film de base comprend une couche de traitement de surface dans laquelle des atomes d'oxygène sont introduits ; et la couche de traitement de surface et la couche de dépolarisation sont en contact direct l'une avec l'autre.
(JA) 基材フィルムと、前記基材フィルムの少なくとも一方の面に形成された、直線偏光を部分偏光又は非偏光に変換する機能を有する偏光解消層と、を備え、前記偏光解消層が、液晶性化合物又は前記液晶性化合物の配向固定化合物を含み、前記基材フィルムが、酸素原子を導入された表面処理層を含み、前記表面処理層と前記偏光解消層とが、直接に接している、偏光解消フィルム。
