摘要:
The present invention provides an organic electroluminescent device using a novel light-emitting material. The organic electroluminescent device of the present invention is formed by using an organic compound having an emission wavelength in a single-body state shorter than that in a solution as a light-emitting material, doping the light-emitting material with a conductive material to form a light-emitting layer in such a manner that the content of the conductive material in the light-emitting layer is lower than that of the light-emitting material therein, and interposing the light-emitting layer between electrodes.
