Abstract
A light-emitting element includes a first electrode, a second electrode disposed on the first electrode, and at least one functional layer disposed between the first electrode and the second electrode. The at least one functional layer includes a charge transport material derived from an azide compound represented by Formula 1 and a polymer compound including an aromatic ring group. The light-emitting element may be formed by a wet process and may exhibit improved flexibility.
Claims20
A light-emitting element comprising:
- a first electrode, a second electrode disposed on the first electrode, and at least one functional layer disposed between the first electrode and the second electrode, the at least one functional layer including a charge transport material that is derived from a mixture of an azide compound represented by Formula 1 and a polymer compound including an aromatic ring group,
- wherein, in Formula 1,
- n1 is an integer of 1 to 9,
- R1 and R2 are each independently a hydrogen atom or an optionally substituted alkyl group having 1 to 10 carbon atoms,
- R3 and R4 are each independently a hydrogen atom or an optionally substituted alkyl group having 1 to 9 carbon atoms.
A display device comprising:
- a base layer, and a light-emitting element disposed on the base layer,
- wherein the light-emitting element comprises:
