| 摘要 |
In an organic light emitting device according to an embodiment of the present invention, the present invention can reduce a driving voltage of the organic light emitting device by mixing a first host composed of a carbazole type material, a second host composed of a metal complex and a dopant and then applying a mixture of the same on a red light emission layer, and therefore, can ameliorate power consumption of the organic light emitting device. Also, the present invention can improve lifespan of the organic light emitting device by improving luminous efficiency of the red light emission layer of the organic light emitting device through mixing and applying of the first host and the second host having an energy level difference on the red light emission layer. |
