Abstract
A light emitting element of one or more embodiments may include a first electrode, a second electrode provided on the first electrode, and at least one functional layer provided between the first electrode and the second electrode. The at least one functional layer may include an amine compound of one or more embodiments, represented by Formula 1. Accordingly, the light emitting element of one or more embodiments may show a low driving voltage, high luminance, high efficiency and long-life characteristics.
Claims20

- and
- at least one functional layer between the first electrode and the second electrode, the at least one functional layer comprising an amine compound represented by Formula 1:
- in Formula 1,
- n1 is an integer of 0 to 2,
- L1 is a direct linkage, or an unsubstituted arylene group of 6 to 30 ring-forming carbon atoms,
- n2 is 0 or 1,
- Ar1 is a substituted or unsubstituted methyl group, a substituted or unsubstituted cyclohexyl group, a substituted or unsubstituted norbornyl group, a substituted or unsubstituted adamantyl group, an unsubstituted phenyl group, an unsubstituted biphenyl group, a substituted or unsubstituted naphthyl group, or a substituted or unsubstituted terphenyl group,
- Ar2 and Ar3 are each independently a substituted or unsubstituted silyl group, a substituted or unsubstituted alkoxy group of 1 to 30 carbon atoms, a substituted or unsubstituted alkyl group of 1 to 30 carbon atoms, a substituted or unsubstituted alkenyl group of 2 to 30 carbon atoms, a substituted or unsubstituted alkynyl group of 2 to 30 carbon atoms, a substituted or unsubstituted aryl group of 6 to 30 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group of 2 to 30 ring-forming carbon atoms, and/or combined with an adjacent group to form a ring, and
- R1 to R8 are each independently a hydrogen atom, a deuterium atom, a cyano group, a nitro group, a hydroxyl group, a halogen atom, a substituted or unsubstituted silyl group, a substituted or unsubstituted alkoxy group of 1 to 30 carbon atoms, a substituted or unsubstituted alkyl group of 1 to 30 carbon atoms, a substituted or unsubstituted alkenyl group of 2 to 30 carbon atoms, a substituted or unsubstituted alkynyl group or 2 to 30 carbon atoms, a substituted or unsubstituted aryl group of 6 to 30 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group of 2 to 30 ring-forming carbon atoms, and/or combined with an adjacent group to form a ring.
