Organic optoelectronic diode and display device

An organic optoelectronic device, comprising

• an anode and a cathode facing each other,
• a light emitting layer between the anode and the cathode,
• a hole transport layer between the anode and the light emitting layer, and
• a hole transport auxiliary layer between the hole transport layer and the light emitting layer,
• wherein the hole transport auxiliary layer includes a first hole transport auxiliary layer adjacent to the hole transport layer and a second hole transport auxiliary layer adjacent to the light emitting layer,
• the first hole transport auxiliary layer includes a first compound represented by Chemical Formula 1, and
• the hole transport auxiliary layer includes a second compound represented by Chemical Formula 2:
• wherein, in Chemical Formula 1,
• L1 to L6 are each independently a single bond, a substituted or unsubstituted C6 to C20 arylene group, or a substituted or unsubstituted C2 to C30 heterocyclic group, and
• Ar1 to Ar6 are each independently a substituted or unsubstituted C6 to C20 aryl group or a substituted or unsubstituted C2 to C30 heterocyclic group;
• wherein, in Chemical Formula 2,
• X1 is O or S,
• L7 to L9 are each independently a single bond, a substituted or unsubstituted C6 to C20 arylene group, or a substituted or unsubstituted C2 to C30 heterocyclic group,
• R1 and R2 are each independently hydrogen, deuterium, a cyano group, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, or a substituted or unsubstituted C2 to C30 heterocyclic group,
• Ar7 and Ar8 are each independently a substituted or unsubstituted C6 to C20 aryl group or a substituted or unsubstituted C2 to C30 heterocyclic group,
• m1 is one of integers of 1 to 4, and
• m2 is one of integers of 1 to 3.
