摘要:
A light emitting device having an anode and a cathode provided on a substrate, and an organic light emitting layer between the anode and the cathode, where the organic light emitting layer includes a light emitting material and a dopant for improving the dispersability thereof. As the dopant, there are employed a light emitting compound and a non-light emitting compound or a current enhancing material. In case of employing the light emitting compound, the composition corresponds to a case of utilizing plural light emitting materials, and, in such case, the light emission wavelengths are preferably mutually closer. Also, evaporation of the light emitting material and the dopant in the same evaporation boat makes it possible to reduce evaporation temperature, thereby improving the dispersability of the light emitting material.
