Title (EN) PHASE DIFFERENCE FILM, ELLIPTICAL POLARIZING PLATE, AND DISPLAY DEVICE USING ELLIPTICAL POLARIZING PLATE
(FR) FILM À DIFFÉRENCE DE PHASE, PLAQUE DE POLARISATION ELLIPTIQUE ET DISPOSITIF D'AFFICHAGE UTILISANT UNE PLAQUE DE POLARISATION ELLIPTIQUE

Abstract:
(EN) The present invention addresses the problems of providing an optical film (phase difference film) that exhibits superior anti-reflection functionality not only in a direction perpendicular to the film, but also at wide angles, providing an optical film which continues to exhibit this functionality even after being exposed to high temperature conditions, and providing an elliptical polarizing plate and a display device using these optical films. The present invention provides an optical film having a first phase difference layer and a second phase difference layer. The first phase difference layer is formed from a cured product of a polymerizable composition comprising: at least one or more types of a compound A having three or more polymerizable groups and satisfying (formula 1); and at least one or more types of a compound B satisfying (formula 2). The second phase difference layer is formed from a cured product of a polymerizable composition comprising at least one or more types of a compound satisfying the (formula 1) and/or the compound B satisfying the (formula 2).
(FR) La présente invention aborde les problèmes de fourniture d'un film optique (film à différence de phase) qui présente une fonctionnalité anti-réflexion supérieure non seulement dans une direction perpendiculaire au film, mais également à des angles larges, la fourniture d'un film optique qui continue à présenter cette fonctionnalité même après avoir été exposé à des conditions de température élevée, et la fourniture d'une plaque de polarisation elliptique et un dispositif d'affichage utilisant ces films optiques. La présente invention concerne un film optique ayant une première et une deuxième couche de déphasage. La première couche de déphasage est formée à partir d'un produit durci d'une composition polymérisable comprenant : au moins un ou plusieurs types d'un composé A ayant trois groupes polymérisables ou plus et satisfaisant (formule 1); et au moins un ou plusieurs types d'un composé B Satisfaisant (formule 2). La deuxième couche de déphasage est formée à partir d'un produit durci d'une composition polymérisable comprenant au moins un ou plusieurs types d'un composé répondant à la formule 1 et/ou le composé B satisfaisant la formule 2.
(JA) 本発明が解決しようとする課題は、フィルムに対し直角方向のみならず、広い角度において反射防止機能に優れる光学フィルム(位相差フィルム)を提供すると共に、高温状態にさらされた後でもその機能を維持し続ける光学フィルムを提供することであり、更にこれらの光学フィルムを用いた楕円偏光板、表示装置を提供することにある。 発明は、第一の位相差層と第二の位相差層とを有する光学フィルムであって、第一の位相差層は、下記(式1)を満たす3つ以上の重合性基を持つ化合物Aを少なくとも1種類以上、及び、下記(式2)を満たす化合物Bを少なくとも1種類以上含有する重合性組成物の硬化物から形成され、第二の位相差層は、(式1)を満たす化合物及び/又は(式2)を満たす化合物Bを少なくとも1種類以上含有する重合性組成物の硬化物から形成された、光学フィルムを提供する。
