Title (EN) PHASE DIFFERENCE FILM
(FR) FILM À DIFFÉRENCE DE PHASE
(JA) 位相差フィルム
Abstract:
(EN) The present invention addresses the problem of providing a phase difference film capable of exhibiting a sufficient reverse wavelength dispersion property. The present invention relates to a phase difference film that comprises a copolymer containing at least one unit selected from a unit represented by general formula (1) and a unit represented by general formula (2), and a unit represented by general formula (3), and satisfies 20 nm < Re(548) < 300 nm, 0.5 < Re(446)/Re(548) < 1.0, and 1.0 < Re(629)/Re(548) < 2.0 where Re(446), Re(548), and Re(629) indicate in-plane retardations at wavelengths of 446 nm, 548 nm, and 629 nm, respectively.
(FR) La présente invention aborde le problème de la fourniture d'un film à différence de phase pouvant présenter une propriété de dispersion de longueur d'onde inverse suffisante. La présente invention concerne un film à différence de phase qui comprend un copolymère contenant au moins une unité choisie parmi une unité représentée par la formule générale (1) et une unité représentée par la formule générale (2), et une unité représentée par la formule générale (3), et qui satisfait à 20 nm < Re(548) < 300 nm, 0,5 < Re(446)/Re(548) < 1,0, et 1,0 < Re(629)/Re(548) < 2,0, où Re(446), Re(548) et Re(629) indiquent des retards dans le plan à des longueurs d'onde de respectivement 446 nm, 548 nm et 629 nm.
(JA) 本発明は、十分な逆波長分散性を発揮し得る位相差フィルムを提供することを課題とする。本発明は、一般式(1)で表される単位及び一般式(2)で表される単位から選択される少なくとも一方と、一般式(3)で表わされる単位と、を含有する共重合体を含み、 20nm<Re(548)<300nmであり、 0.5<Re(446)/Re(548)<1.0であり、 1.0<Re(629)/Re(548)<2.0である位相差フィルムに関する。 但し、Re(446)、Re(548)、Re(629)は、それぞれ波長446nm、548nm、629nmにおける面内のレタデーションを表す。
