Luminescent material for organic optoelectric device and organic optoelectric device and display device

A luminescent material for an organic optoelectric device, the luminescent material being represented by the Chemical Formula 1:

• wherein, in Chemical Formula 1,
• each Z is independently N or CRa,
• at least two Zs are N, at least two Zs in the Z-containing ring bonded to L or the triphenylene group being N,
• R1 to R10 and Ra are each independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C6 to C12 aryl group, or a combination thereof,
• L is a substituted or unsubstituted phenylene group, a substituted or unsubstituted biphenylene group, or a substituted or unsubstituted terphenylene group,
• n1 to n3 are each independently 0 or 1, and
• n1+n2+n3≧1.
