Title (EN) OPTICAL LAMINATE, POLARIZING FILM, AND IMAGE DISPLAY DEVICE
(FR) STRATIFIÉ OPTIQUE, FILM POLARISANT ET DISPOSITIF D'AFFICHAGE D'IMAGE
(JA) 光学積層体、偏光フィルムおよび画像表示装置
Abstract:
(EN) The present invention is an optical laminate in which a polarizer is adhered, via an adhesive layer, to a substrate containing an ion component, wherein the ion component is eluted on the adhesive layer side of the substrate, and a transparent blocking layer for suppressing the migration of the ion component to the polarizer side is provided between the polarizer and the substrate. This optical laminate is capable of preventing the reduction of optical properties even in high temperature, high humidity environments.
(FR) La présente invention concerne un stratifié optique dans lequel un polariseur est collé, par l'intermédiaire d'une couche adhésive, à un substrat contenant un composant ionique, le composant ionique étant élué sur le côté couche adhésive du substrat, et une couche de blocage transparente servant à supprimer la migration du composant ionique vers le côté polariseur est disposée entre le polariseur et le substrat. Ledit stratifié optique est apte à empêcher la réduction de propriétés optiques même dans des environnements à température élevée et humidité élevée.
(JA) 本発明は、偏光子が、粘着剤層を介して、イオン成分を含有する基板に貼り合されている光学積層体であって、前記基板は、イオン成分を粘着剤層側に溶出するものであり、かつ、前記偏光子と前記基板の間に、前記イオン成分の偏光子側への移行を抑える透明ブロック層を有する。本発明の光学積層体は、高温高湿環境下においても、光学特性の低下を抑えることができる。
