| description | To provide a film which can reduce retardation in a thickness direction without subjected to graft polymerization.SOLUTION: A film is formed of a resin composition containing a polymer (A) having a diene and/or olefin-derived unit, and a (meth)acrylic polymer (B) having a ring structure in a main chain, in which the chain of the polymer (B) is not grafted with the chain of the polymer (A), and an NZ coefficient of the film determined from NZ coefficient=(Rth/Re)+0.50 (Re is in-plane retardation (nm) at wavelength of 589 nm, and Rth is thickness direction retardation (nm) at wavelength of 589 nm) is 0.1 to 0.6.SELECTED DRAWING: None
【課題】グラフト重合を行うことなく、厚さ方向の位相差を小さくすることが可能なフィルムを提供する。【解決手段】ジエンおよび／またはオレフィン由来の単位を有するポリマー（Ａ）と主鎖に環構造を有する（メタ）アクリル系ポリマー（Ｂ）とを含有する樹脂組成物から形成されたフィルムであって、前記ポリマー（Ａ）の鎖に前記ポリマー（Ｂ）の鎖はグラフトしておらず、ＮＺ係数＝（Ｒｔｈ／Ｒｅ）＋０．５０（ここで、Ｒｅは波長５８９ｎｍにおける面内位相差（ｎｍ）であり、Ｒｔｈは波長５８９ｎｍにおける厚さ方向位相差（ｎｍ）である。）から求められる前記フィルムの前記ＮＺ係数が０．１～０．６であることを特徴とするフィルム。【選択図】なし |
