Title (EN) OPTICAL FILM, LAMINATED FILM UTILIZING SAME, AND METHOD OF MANUFACTURING OPTICAL FILM
(FR) FILM OPTIQUE, FILM STRATIFIÉ L'UTILISANT, ET PROCÉDÉ DE FABRICATION DE FILM OPTIQUE
(JA) 光学フィルム及びそれを用いた積層フィルム、並びに光学フィルムの製造方法
Abstract:
(EN) One purpose of the present invention is to provide an optical film in which the formation of defects such as creases and scratches during handling is inhibited. Another purpose of the present invention is to provide a flexible device front plate and flexible device that utilize the optical film. Provided is an optical film containing a polyimide polymer, an end surface of the optical film being a slanted surface having an angle of 5° to 75° with respect to the surface of the optical film.
(FR) Un but de la présente invention est de fournir un film optique dans lequel la formation de défauts tels que des plis et des rayures pendant la manipulation est inhibée. Un autre but de la présente invention est de fournir une plaque avant de dispositif flexible et un dispositif flexible qui utilisent le film optique. L'invention concerne un film optique contenant un polymère de polyimide, une surface d'extrémité du film optique étant une surface inclinée ayant un angle de 5° à 75° par rapport à la surface du film optique.
(JA) 本発明は、取り扱い時に折れ跡やキズといった欠陥が発生しにくい光学フィルムを提供することを目的とする。また、本発明は、上記光学フィルムを用いたフレキシブルデバイス用前面板及びフレキシブルデバイスを提供することを目的とする。 ポリイミド系高分子を含有する光学フィルムであって、上記光学フィルムの端面が、上記光学フィルムの表面に対して5°以上75°以下の角度で傾斜した傾斜面である、光学フィルム。
