Abstract

　溶液流延製膜法による光学フィルムの製造方法において、剥離後のフィルムの搬送トラブルや、フィルムの押され故障の発生、ロール表面温度低下によるコンデンス故障の発生を防止し、高延伸にしても、フィルムのヘイズが高くならず、透明性、平面性に優れ、さらに、液晶表示装置に組み込んだ際のコントラストの向上が可能となる、光学フィルム、偏光板、及び表示装置を提供する。 　樹脂溶液（ドープ）を金属支持体上に流延して流延膜（ウェブ）を形成し、溶剤の一部を蒸発させた後に、金属支持体から剥離する工程と、剥離したウェブの両端部を把持して、延伸することなく搬送しながら乾燥する把持乾燥工程と、ついでウェブを幅手方向に延伸する工程とを備え、ウェブが剥離されてから、つぎの工程においてウェブ両端部が把持されるまでの間に、ウェブに含まれる残留溶媒量の減少量が、５～１５質量％となされている。
