1. An organic light-emitting diode comprising:
a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode, the organic layer comprising an emission layer comprising at least one light-emitting material represented by Formula 1 below, and a region between the first electrode and the emission layer comprising at least one hole transport material represented by one of Formulae 2 to 4 below: wherein, in Formulae 1 to 4: X1 is CR1 or N; X2 is CR2 or N; X3 is CR3 or N; X4 is CR4 or N; X5 is CR5 or N; X6 is CR6 or N; X7 is CR7 or N; X8 is CR8 or N; X9 is CR9 or N; X10 is CR10 or N; X11 is CR11 or N; X12 is CR12 or N; R1 to R22 are each independently selected from a hydrogen atom, a deuterium atom, a halogen atom, a hydroxyl group, a cyano group, a nitro group, an amino group, an amidino group, a hydrazine, a hydrazone, a carboxylic acid group or a salt thereof, a sulfonic acid group or a salt thereof, a phosphoric acid group or a salt thereof, a substituted or unsubstituted C1-C60alkyl group, a substituted or unsubstituted C2-C60alkenyl group, a substituted or unsubstituted C2-C60alkynyl group, a substituted or unsubstituted C1-C60alkoxy group, a substituted or unsubstituted C3-C10cycloalkyl group, a substituted or unsubstituted C2-C10heterocycloalkyl group, a substituted or unsubstituted C3-C10cycloalkenyl group, a substituted or unsubstituted C2-C10heterocycloalkenyl group, a substituted or unsubstituted C6-C60aryl group, a substituted or unsubstituted C6-C60aryloxy group, a substituted or unsubstituted C8-C60arylthio group, and a substituted or unsubstituted C2-C60heteroaryl group; a1 and a2 are each independently selected from an integer from 0 to 3, wherein, when a1 is an integer of 2 or greater, a plurality of R17s are the same or different, and when a2 is an integer of 2 or greater, a plurality of R18s are the same or different; Ar1 to Ar9 are each independently selected from a substituted or unsubstituted C3-C10cycloalkylene group, a substituted or unsubstituted C2-C10heterocycloalkylene group, a substituted or unsubstituted C3-C10cycloalkenylene group, a substituted or unsubstituted C2-C10heterocycloalkenylene group, a substituted or unsubstituted C6-C60arylene group, and a substituted or unsubstituted C2-C60heteroarylene group; L1 to L3 are each independently selected from a substituted or unsubstituted C3-C10cycloalkylene group, a substituted or unsubstituted C2-C10heterocycloalkylene group, a substituted or unsubstituted C3-C10cycloalkenylene group, a substituted or unsubstituted C2-C10heterocycloalkenylene group, a substituted or unsubstituted C6-C60arylene group, and a substituted or unsubstituted C2-C60heteroarylene group; n1 to n3 are each independently selected from an integer from 0 to 5, wherein, when n1 is an integer of 2 or greater, a plurality of L1s are the same or different, when n2 is an integer of 2 or greater, a plurality of L2s are the same or different, and when n3 is an integer of 2 or greater, a plurality of L3 s are the same or different; and Y is selected from a substituted or unsubstituted C2-C10heterocycloalkyl group, a substituted or unsubstituted C2-C10heterocycloalkenyl group, and a substituted or unsubstituted C2-C30heteroaryl group. |
