Abstract:
(EN) Provided is an optical member capable of contributing to improvement of contrast of an image display device when used in the image display device. The optical member according to the present invention has a polarizer, a reflective polarizer, and a low-refractive-index layer with a refractive index of 1.25 or less. The low-refractive-index layer is stacked on at least one side of the polarizer. In the optical member, the reflective polarizer, the polarizer, and the low-refractive-index layer are typically integrated together in this order.
(FR) L'invention concerne un élément optique permettant de contribuer à l'amélioration du contraste d'un dispositif d'affichage d'image lorsqu'il est utilisé dans le dispositif d'affichage d'image. L'élément optique selon la présente invention comprend un polariseur, un polariseur réfléchissant et une couche à faible indice de réfraction ayant un indice de réfraction inférieur ou égal à 1,25. La couche à faible indice de réfraction est empilée sur au moins un côté du polariseur. Dans l'élément optique, le polariseur réfléchissant, le polariseur et la couche à faible indice de réfraction sont généralement intégrés ensemble dans cet ordre.
(JA) 画像表示装置に用いた場合に画像表示装置のコントラストの向上に寄与し得る光学部材を提供する。本発明の光学部材は、偏光子と、反射型偏光子と、屈折率が1.25以下である低屈折率層と、を有し、低屈折率層が偏光子の少なくとも片側に積層されている。光学部材は、代表的には、反射型偏光子と、偏光子と、低屈折率層と、がこの順に一体化されている。
