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 including quantum dots. The quantum dots include a core and a shell. Each of the core and the shell includes at least two selected from Mg, Zn, Te, Se, and S. When the quantum dots include Mg, a content of Mg in the shell is greater than a content of Mg in the core.
