Abstract
Description
波長400nm程度の青色レーザを情報の記録又は再生に使用する光記録装置においては、金やシリコン薄膜は、それらの記録媒体の反射膜として、青色光に対する吸収が大きいため十分な反射率を得ることができない。また、銀合金は十分な反射率を得ることが可能であるがコストが高くなる。

本発明による光記録媒体は、これに限定されるものではないが、1つの例として、再生専用型ディスクについて説明する。
有機EL素子は、透明基板上に、透明電極と、有機EL媒体と、金属電極とが順次積層されて構成される。例えば、有機EL媒体は、有機発光層の単一層、あるいは有機正孔輸送層、有機発光層及び有機電子輸送層の3層構造の媒体、又は有機正孔輸送層及び有機発光層2層構造の媒体、さらにこれらの適切な層間に電子或いは正孔の注入層を挿入した積層体の媒体などである。本発明の多結晶アルミニウム薄膜はかかる金属電極として有効に使用できる。
