The present invention relates to a novel organic electroluminescent compound and an organic electroluminescent device comprising the same. When the organic electroluminescent compound according to the present invention is used as a phosphorescent host material, a hole transport material, and a mixed host material, the electron transport efficiency is high so that crystallization can be prevented when manufacturing the device, and since they are adaptable in the formation of the layers, the current characteristic of the device is improved, and finally it is possible to manufacture an OLED device of lowered driving voltages and advanced power efficiency. |
