Claims13
A light emitting element comprising:
- a first electrode;
- a second electrode on the first electrode;
- and
- at least one functional layer between the first electrode and the second electrode and comprising an amine compound represented by Formula 1-A1:
- wherein, in Formula 1-A1,
- L1 is a direct linkage, a substituted or unsubstituted arylene group having 6 to 30 carbon atoms for forming a ring, or a substituted or unsubstituted heteroarylene group having 2 to 30 carbon atoms for forming a ring,
- n1 and n2 are each independently an integer of 0 to 3,
- Ar1 and Ar2 are each independently a hydrogen atom, a deuterium atom, a substituted or unsubstituted aryl group having 6 to 30 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group having 2 to 30 ring-forming carbon atoms, and
- Ar3 and Ar4 are each independently a substituted or unsubstituted aryl group having 6 to 30 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group having 2 to 30 ring-forming carbon atoms.
