あるいは、電子注入層に、有機化合物と電子供与体(ドナー)とを混合してなる複合材料を用いてもよい。このような複合材料は、有機化合物が電子供与体から電子を受け取るため、電子注入性および電子輸送性に優れている。この場合、有機化合物としては、受け取った電子の輸送に優れた材料であることが好ましく、具体的には、例えば上述した電子輸送層を構成する材料(金属錯体や複素芳香族化合物等)を用いることができる。電子供与体としては、有機化合物に対し電子供与性を示す材料であればよい。具体的には、アルカリ金属、アルカリ土類金属及び希土類金属が好ましく、リチウム、セシウム、マグネシウム、カルシウム、エルビウム、イッテルビウム等が挙げられる。また、アルカリ金属酸化物やアルカリ土類金属酸化物が好ましく、リチウム酸化物、カルシウム酸化物、バリウム酸化物等が挙げられる。また、酸化マグネシウムのようなルイス塩基を用いることもできる。また、テトラチアフルバレン(略称:TTF)等の有機化合物を用いることもできる。

スペース層は発光層間に設けられるため、電子輸送性と正孔輸送性を兼ね備える材料であることが好ましい。また、隣接する燐光発光層内の三重項エネルギーの拡散を防ぐため、三重項エネルギーが2.6eV以上であることが好ましい。スペース層に用いられる材料としては、上述の正孔輸送層に用いられるものと同様のものが挙げられる。
発光層に隣接する部分に、電子阻止層、正孔阻止層、トリプレット阻止層などの阻止層を設けてもいい。電子阻止層とは発光層から正孔輸送層へ電子が漏れることを防ぐ層であり、正孔阻止層とは発光層から電子輸送層へ正孔が漏れることを防ぐ層であり、本発明の有機EL素子では第1電子輸送層が正孔阻止層として機能する。トリプレット阻止層は発光層で生成した励起子が周辺の層へ拡散することを防止し、励起子を発光層内に閉じ込める機能を有する。
