| description | The present invention addresses the problem of providing: an optical film which has improved orientation of a liquid crystal compound in an optical anisotropic layer while suppressing the occurrence of bright spot defects; an optically anisotropic layer; an alignment film-forming composition; a method for producing an optical film; a polarizing plate; and an image display device. An optical film according to the present invention has an alignment film and an optically anisotropic layer, wherein: the optically anisotropic layer is a layer formed using an optically anisotropic layer-forming composition containing a polymerizable liquid crystal compound; and the alignment film is a film formed using an alignment film-forming composition containing an additive having a C5-C29 alkyl group and a polymer having no C5-C29 alkyl group.
La présente invention aborde le problème consistant à fournir : un film optique qui a une orientation améliorée d'un composé de cristaux liquides dans une couche anisotrope optique tout en supprimant l'apparition de défauts de point brillant ; une couche optiquement anisotrope ; une composition de formation de film d'alignement ; un procédé de production d'un film optique ; une plaque de polarisation ; et un dispositif d'affichage d'image. Un film optique selon la présente invention a un film d'alignement et une couche optiquement anisotrope, la couche optiquement anisotrope étant une couche formée à l'aide d'une composition de formation de couche optiquement anisotrope contenant un composé de cristaux liquides polymérisable ; et le film d'alignement étant un film formé à l'aide d'une composition de formation de film d'alignement contenant un additif ayant un groupe alkyle en C5-C29 et un polymère n'ayant pas de groupe alkyle en C5-C29.
本発明は、光学異方性層における液晶化合物の配向性が良好となり、かつ、輝点欠陥の発生が抑制された光学フィルム、光学異方性層、配向膜形成用組成物、光学フィルムの製造方法、偏光板および画像表示装置を提供することを課題とする。本発明の光学フィルムは、配向膜と、光学異方性層とを有する光学フィルムであって、光学異方性層が、重合性液晶化合物を含有する光学異方性層形成用組成物を用いて形成された層であり、配向膜が、炭素数５～２９のアルキル基を有する添加剤と、炭素数５～２９のアルキル基を有さないポリマーとを含有する配向膜形成用組成物を用いて形成された膜である、光学フィルムである。 |
