摘要

In the organic light emitting device including an organic layer disposed between the lower electrode (101), an upper electrode (102), a lower electrode (101) upper electrode (102) and a (103), the organic layer ( The 103), is provided mixed layer and a charge transport layer (10), in contact with (10) a charge transport layer (11), the mixing layer (11) comprises a host, a charge transporting material and a first dopant The configuration, the first dopant, included functional groups of the first, the charge transporting material, and contained functional groups of a second, the first dopant, the mixed layer (11) is charged a structure which is attracted to the charge transport layer contact surface is the surface on the side in contact with (10) the transport layer, the charge transport material and a structure which is attracted to the surface of the charge transport layer contact surface other than the (11) mixed layer to. In accordance with the present invention, it is possible to control easily the concentration of the molecules emitting layer and contained in the mixed layer of the charge transport layer.
