反射防止フィルム、その製造方法及び画像表示装置

Antireflection film, method of manufacturing same and image display device

Abstract

<P>PROBLEM TO BE SOLVED: To provide an antireflection film which is improved in film strength and chemical resistance and is suppressive in variation of reflection color and the occurrence of unevenness, and to provide a method of manufacturing the same and an image display device using the antireflection film. <P>SOLUTION: The method, by which an antireflection layer containing metal oxide fine particles and a binder as main components is formed on a transparent support film by application, is characterized in that, before the antireflection layer is formed, discharge is generated by applying a high frequency voltage having 50 kHz to 150 MHz frequency between facing electrodes under the atmospheric pressure or a pressure in the vicinity thereof and an excited gas formed by the discharge is brought into contact with the surface of the transparent support film. <P>COPYRIGHT: (C)2007,JPO&INPIT
【課題】膜強度、耐薬品性を改善するとともに、反射色変動、ムラの発生が抑制された反射防止フィルム、その製造方法及び該反射防止フィルムを用いた画像表示装置を提供することにある。 【解決手段】透明支持体フィルムの上に主成分として金属酸化物微粒子とバインダーを含有する反射防止層を塗布により形成する反射防止フィルムの製造方法において、前記反射防止層の形成前に、大気圧またはその近傍の圧力下で、対向する電極の間に周波数が50kHz〜150MHzの高周波電圧を印加して放電を形成し、該放電により形成された励起ガスを前記透明支持体フィルムの表面に接触させることを特徴とする反射防止フィルムの製造方法。 【選択図】なし
