Abstract: A light emitting element may include a first electrode, an electron transport region on the first electrode and including metal nanoparticles, an emission layer on the electron transport region and including quantum dots, a hole transport region on the emission layer, and a second electrode disposed on the hole transport region. The metal nanoparticle may include a core including a metal oxide composed of zinc (Zn), magnesium (Mg), oxygen (O) and a first component, and a ligand bonded to the core and derived from an ionic compound represented by Formula 1. The first component may include sodium (Na) or lithium (Li). Accordingly, the light emitting element of an embodiment may show high efficiency and long lifetime.
