Abstract
A light emitting element includes a first electrode, a second electrode overlapping the first electrode, and an emission layer between the first electrode and the second electrode. The emission layer includes a quantum well that includes a first layer and a second layer, each having a different band gap. The first layer includes magnesium, and the second layer includes zinc. The first layer and the second layer are amorphous.
