Abstract

　燐光発光層（５１，５２）は、燐光用ホストと燐光発光を示す燐光用ドーパントとを有し、蛍光発光層（７）は、蛍光用ホストと蛍光発光を示す蛍光用ドーパントとを有する。電荷障壁層（６）は、蛍光発光層（７）の蛍光用ホストに注入された電子が蛍光発光層（７）から電荷障壁層（６）側に注入されるのをブロックし、かつ、正孔を燐光発光層（５１，５２）から蛍光発光層（７）に注入させる。燐光発光層（５１，５２）の燐光用ドーパントの三重項エネルギーギャップＥｇＰＤと、電荷障壁層（６）の三重項エネルギーギャップＥｇＥＢと、蛍光発光層（７）の蛍光用ホストの三重項エネルギーギャップＥｇＦＨとは、次の式（１）を満たす。 ＥｇＰＤ＜ＥｇＥＢ≦ＥｇＦＨ　　（１）
