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、金属支持体の表面に大気圧プラズマ処理またはエキシマＵＶ処理により表面処理膜を形成した後に、金属支持体表面にドープを流延することで、金属支持体の剥離性不良領域を解消することができる。これにより、フィルム生産条件の制約が減り、生産性が向上する。さらに、フィルムの剥離性が向上することで、剥離位置の幅手方向の変動が減少するとともに、リタデーション値のばらつきが大幅に低減するので、透明性、平面性に優れた光学特性を有する光学フィルムを製造することができる。これにより、偏光板用保護フィルム等の薄膜化、広幅化及び高品質化の要求に応えることができる光学フィルムの製造方法、光学フィルム、偏光板及び表示装置を提供することができる。
