In an organic electroluminescent device constructed by providing at least an emitting layer using an organic material between a hole injection electrode and an electron injection electrode, in forming an emitting layer having a dopant doped into a host material, a dopant having a condensed ring obtained by condensing three or more rings is used, and the difference between the highest occupied molecular orbital in the host material and the highest occupied molecular orbital in the dopant is in a range from - 0.3 eV to + 0.3 eV.
在一种通过在空穴注入电极和电子注入电极之间提供至少一个使用有机材料的发光层而构建的有机电致发光器件中,在形成具有掺杂到宿主材料中的掺杂剂的发光层时,使用了具有通过缩合三个或更多环而获得的缩合环的掺杂剂,并且宿主材料中的最高占据分子轨道与掺杂剂中的最高占据分子轨道之间的差值在 - 0.3 eV 至 + 0.3 eV 的范围内。
