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.
