Title (EN) RETARDATION FILM AND PRODUCTION METHOD
(FR) FILM DE DÉPHASAGE, ET PROCÉDÉ DE FABRICATION ASSOCIÉ
(JA) 位相差フィルム及び製造方法
Abstract:
(EN) A retardation film and a production method therefor, said retardation film: substantially comprising only one type of copolymer P including a polymerization unit A and a polymerization unit B; having a phase-separated structure exhibiting structural birefringence; and having an NZ coefficient greater than 0 and less than 1. Ideally: the phase-separated structure includes a phase having the polymerization unit A as the main component thereof and a phase having the polymerization unit B as the main component thereof; the phase-separated structure has a lamellar, cylindrical, or spheroid form; and the inter-phase distance in the phase-separated structure is no more than 200 nm.
(FR) L’invention concerne un film de déphasage et un procédé de fabrication de celui-ci. Ce film de déphasage est constitué en pratique uniquement d’une sorte de copolymère (P) contenant une unité polymère (A) et une unité polymère (B), et possède une structure de séparation de phases exprimant une biréfringence structurale. Le film de déphasage présente un coefficient NZ supérieur à 0 et inférieur à 1. De préférence, ladite structure de séparation de phases contient une phase ayant pour composant principal ladite unité polymère (A), et une phase ayant pour composant principal ladite unité polymère (B), ladite structure de séparation de phases présente la forme d’une lamelle, d’un cylindre ou d’un sphéroïde, et la distance interphase dans ladite structure de séparation de phases est inférieure ou égale à 200nm.
(JA) 重合単位Aと重合単位Bとを含む1種の共重合体Pのみから実質的になり、構造性複屈折を発現する相分離構造を有し、0より大きく、且つ1より小さいNZ係数を有する、位相差フィルム;並びにその製造方法。好ましくは、前記相分離構造が、前記重合単位Aを主成分とする相と、前記重合単位Bを主成分とする相とを含み、前記相分離構造が、ラメラ、シリンダ、スフェロイドのいずれかの形態を有し、前記相分離構造における相間距離が200nm以下である。
