Description
図1に、本実施形態1に係る反射防止膜1の模式的断面図を示す。反射防止膜1は、図1に示すように、透明性基板であるガラス基板15上に形成されている。本実施形態1に係る反射防止膜1は、ガラス基板15の直上に形成されている例を示しているが、ガラス基板15と反射防止膜1の間に、他の積層膜が積層されていてもよい。本実施形態1に係る反射防止膜1は、単一層により構成されている。
次に、上記実施形態1とは異なる反射防止膜の一例について説明する。なお、以降の説明において、上記実施形態1と同一の要素部材には同一の符号を付し、適宜その説明を省略する。
本実施形態3に係る反射防止膜は、以下の点を除く基本的な構成及び製造方法は、上記実施形態2と同様である。すなわち、上記実施形態2に係る反射防止膜2は、Al系N含有膜2a、Al系膜2bの2層構造であったのに対し、本実施形態3に係る反射防止膜3は、3層構造である点において相違する。
次に、本発明に係る反射防止膜を、液晶表示装置に適用した例について説明する。本実施形態4においては、本発明に係る反射防止膜を、TN(Twisted Nematic)モードの液晶表示装置のカラーフィルター基板に適用した例について説明する。
本発明に係る反射防止膜を、液晶表示装置のアクティブマトリックス基板に適用した例について説明する。本実施形態5に係る液晶表示装置は、上記実施形態4と同様のTNモードとする。
本発明による反射防止膜を、液晶をパネル面に対して概略平行方向に配向させるIPS(In Plane Switching)モードの液晶表示装置に適用した例について説明する。図21は、本実施形態6に係るアクティブマトリックス基板30aの一部を示す模式的平面図、図22は、図21中のXXII-XXII切断部断面図である。なお、上記実施形態5と同一の要素部材には同一の符号を付し、適宜その説明を省略する。
本実施形態7に係る反射防止膜は、以下の点を除く基本的な構成及び製造方法は、上記実施形態2と同様である。すなわち、上記実施形態2に係る反射防止膜2は、第1薄膜として機能するAl系N含有膜2aがN元素を添加したものであったのに対し、本実施形態7に係る反射防止膜7は、第1薄膜として機能するAl系N含有膜が、N元素の他に、さらにO元素を添加したものである点において相違する。なお、以降の説明において、N元素の他にさらにO元素を添加したAl系N含有膜を、説明の簡便化の観点から「Al系N+O含有膜」とも称する。
