ORGANIC OPTOELECTRIC DEVICE AND DISPLAY DEVICE

摘要

The present invention relates to an organic photoelectric device and a display device including the same. The organic photoelectric device comprises: an anode and a cathode which face each other; a light-emitting layer disposed between the anode and the cathode; a hole transportation layer disposed between the anode and the light-emitting layer; a hole transportation assisting layer disposed between the hole transportation layer and the light-emitting layer; an electron transportation layer disposed between the cathode and the light-emitting layer; and an electron transportation assisting layer disposed between the electron transportation layer and the light-emitting layer. The electron transportation assisting layer includes at least one first compound represented by chemical formula 1, and the hole transportation assisting layer includes at least one second compound represented by chemical formula 2. Chemical formulas 1 and 2 are the same as described in the specification. High efficiency and long lifespan may be ensured.
