    • [It is an object] to provide an organic electroluminescent element with which the initial durability of the element can be greatly improved while maintaining the efficiency of the element at a high level. This is an organic electroluminescent element having an anode, a hole injection layer, a first hole transport layer, a second hole transport layer, a light-emitting layer, and a cathode, in this order, with this organic electroluminescent element being such that the aforementioned hole injection layer includes a material for which the energy of the lowest unoccupied molecular orbital (LUMO) is less than −4.0 eV and also such that the energy E1(LUMO) of the LUMO of the material included in the aforementioned first hole transport layer and the energy E2(LUMO) of the LUMO of the material included in the aforementioned second hole transport layer satisfy [the inequality] E1(LUMO)>E2(LUMO).
    • 本发明是提供一种有机电致发光元件,通过该有机电致发光元件可以极大地提高元件的初始耐久性,同时将元件的效率保持在高水平。 这是一种具有阳极,空穴注入层,第一空穴传输层,第二空穴传输层,发光层和阴极的有机电致发光元件,该有机电致发光元件使得 上述空穴注入层包括最低未占分子轨道(LUMO)的能量小于-4.0eV的材料,并且还使得包含在上述第一空穴传输层中的材料的LUMO的能量E1(LUMO) 并且包含在上述第二空穴传输层中的材料的LUMO的能量E2(LUMO)满足[不等式] E1(LUMO)> E2(LUMO)。
