ORGANIC OPTOELECTRIC DEVICE AND DISPLAY DEVICE

摘要

The present invention relates to an organic optoelectronic element and a display device. The organic optoelectronic device comprises: an anode and a cathode facing each other; a light emitting layer disposed between the anode and the cathode; a hole transport layer disposed between the anode and the light emitting layer; and a hole transport auxiliary layer disposed between the hole transport layer and the light emitting layer. The light emitting layer comprises a first compound of at least one represented by chemical formula 1 and a second compound of at least one represented by chemical formula 2. In addition, the hole transport layer comprises a third compound represented by a combination of a moiety represented by chemical formula 3, a moiety represented by chemical formula 4, and a moiety represented by chemical formula 5. The chemical formula 1 to the chemical formula 5 are the same as described in the specification.
