摘要：
It is an object of the present invention to provide an organic light-emitting device which can emit white light by easily controlling dopant concentrations. The organic light-emitting device has a first electrode (112) and second electrode (111) which hold a light-emitting layer (113) in-between, wherein the light-emitting layer contains a host material (104), red-light-emitting dopant (105), green-light-emitting dopant (106) and blue-light-emitting dopant (107), the red-light-emitting dopant containing a first functional group for transferring the dopant toward the first electrode and the green-light-emitting dopant containing a second functional group for transferring the dopant toward the second electrode.
