Method for manufacturing organic electroluminescent device and white light emitting organic electroluminescent device

摘要

The present invention relates to a method for producing an organic electroluminescence device comprising at least an anode, a light emitting layer, and a cathode, wherein the light emitting layer comprises one layer containing at least two kinds of light emitting dopants, and at least the anode, the light emitting layer, and the It is characterized in that it has a step of performing an annealing process after the cathode is formed as an element structure. According to the method of the present invention, it is possible to stably produce an organic electroluminescence device having a high luminous efficiency and a long lifetime, and it is suitable for the production of a white light emitting organic electroluminescence device.
