Title (EN) OPTICAL LAYERED BODY AND DISPLAY DEVICE
(FR) CORPS MULTICOUCHE OPTIQUE ET DISPOSITIF D'AFFICHAGE
(JA) 光学積層体及び表示装置
Abstract:
(EN) The present invention is: an optical layered body including at least two types of films, wherein the optical layered body includes at least a film A satisfying a predetermined condition (1) and a film C satisfying a predetermined condition (2), the retardation value Re(0) observed from the direction of an axis perpendicular to the surface of the optical layered body is 4,000-30,000 nm, and the retardation value Re(40) observed in a plane along the slow axis, which is the direction in which the refractive index is greatest in the plane of the film A and perpendicular to the optical layered body surface, from the direction of an axis inclined 40 degrees toward the slow axis from the axis perpendicular to the optical layered body surface is 4,000-25,000 nm; and a display device having the optical layered body.
(FR) La présente invention est : un corps stratifié optique comprenant au moins deux types de films, le corps stratifié optique comprenant au moins un film a satisfaisant une condition prédéterminée (1) et un film C satisfaisant une condition prédéterminée (2), la valeur de retard Re (0) observée à partir de la direction d'un axe perpendiculaire à la surface du corps stratifié optique est de 4000 à 30 000 nm, et la valeur de retard Re (40) observé dans un plan le long de l'axe lent, qui est la direction dans laquelle l'indice de réfraction est le plus grand dans le plan du film a et perpendiculaire à la surface du corps stratifié optique, à partir de la direction d'un axe incliné de 40 degrés vers l'axe lent à partir de l'axe perpendiculaire à la surface du corps stratifié optique est de 4000 à 25 000 nm; et un dispositif d'affichage ayant le corps stratifié optique.
(JA) 少なくとも2種のフィルムを含む光学積層体であって、前記光学積層体は少なくとも、所定の条件(1)を満たすフィルムAと、所定の条件(2)を満たすフィルムCとを含み、該光学積層体面に対し垂直軸方向から観測されるリタデーション値Re(0)が4,000~30,000nmであり、該光学積層体面に対し垂直でかつ該フィルムAの面内において屈折率が最も大きい方向である遅相軸に沿った面内で、該光学積層体面の垂直軸から該遅相軸方向に40度傾斜した軸方向から観測されるリタデーション値Re(40)が4,000~25,000nmである光学積層体、及び該光学積層体を有する表示装置。
