Abstract: front page image
(EN) The problem of the present invention is to provide an optical film having an optically anisotropic layer with excellent durability, and to provide a polarizing plate and an image display device that use the optical film. This optical film is provided with at least an optically anisotropic layer, wherein the optically anisotropic layer is obtained by polymerizing a polymerizable liquid crystal composition that includes a prescribed liquid crystalline compound and a polymerization initiator, the density of the optically anisotropic layer is at least 1.20 g/cm3, and the crosslink density of the layer is at least 0.0016 mol/cm3.
(FR) Le problème décrit par la présente invention est de fournir un film optique ayant une couche optiquement anisotrope avec une excellente durabilité, et de fournir une plaque polarisante et un dispositif d'affichage d'image qui utilisent le film optique. Ce film optique comporte au moins une couche optiquement anisotrope, la couche optiquement anisotrope étant obtenue par polymérisation d'une composition de cristaux liquides polymérisable qui comprend un composé cristallin liquide prescrit et un initiateur de polymérisation. La densité de la couche optiquement anisotrope est d'au moins 1,20 g/cm3, et la densité de réticulation de la couche est d'au moins 0,0016 mole/cm3.
(JA) 本発明の課題は、耐久性に優れた光学異方性層を有する光学フィルムならびにそれを用いた偏光板および画像表示装置を提供することである。本発明の光学フィルムは、少なくとも光学異方性層を有する光学フィルムであって、光学異方性層が、所定の液晶性化合物と重合開始剤とを含有する重合性液晶組成物を重合して得られる層であり、光学異方性層の密度が1.20g/cm3以上であり、かつ、架橋点密度が0.0016mol/cm3以上である、光学フィルムである。
