Title (EN) RETARDATION FILM COMPOSED OF PHOTO-ALIGNED LIQUID CRYSTALLINE POLYIMIDE AND OPTICAL ELEMENT
(FR) FILM À RETARD COMPOSÉ DE POLYIMIDE CRISTALLIN LIQUIDE PHOTO-ALIGNÉ ET ÉLÉMENT OPTIQUE
(JA) 光配向した液晶性ポリイミドによる位相差膜及び光学素子
Abstract: front page image
(EN)Disclosed is a technique which enables the production of a retardation film, wherein regions having different characteristics for the optical axis and/or retardation are patterned, with less load. Specifically, a retardation film is configured of a liquid crystalline polyimide film that has a photoreactive group. Also disclosed are an optical element and a liquid crystal display device each comprising the retardation film.
(FR)L'invention présente une technique permettant la production d'un film à retard, dans lequel des régions ayant différentes caractéristiques d'axe optique et/ou de retard sont configurées en motif, tout en ayant une charge inférieure. Plus précisément, un film à retard est constitué d'un film de polyimide cristallin liquide qui possède un groupe photoréactif. La présente invention concerne également un élément optique et un dispositif d'affichage à cristaux liquides comprenant chacun le film à retard.
(JA)光軸、レタデーションのいずれか一方あるいは両方の特性が異なる領域がパターン化した位相差膜をより少ない負荷で製造できる技術を提供する。 光反応性基を有する液晶性ポリイミド膜から位相差膜を構成する。またこの位相差膜を有する光学素子や液晶表示装置を提供する。
