Abstract
A light-emitting element includes an EML and an HTL, in which the EML includes a base material and a plurality of QDs, the base material includes a base compound including at least one kind of first group VI element as a main component and includes at least one kind of second group VI element having a smaller period number than the first group VI element, and a concentration of the sum of the second group VI elements in the base material is in a range from 1×1016 atoms/cm3 to 1×1020 atoms/cm3.
Claims24
A light-emitting element comprising:
- a light-emitting layer;
- and
- a hole transport layer provided adjacent to the light-emitting layer,
- wherein the light-emitting layer includes a base material including at least one kind of inorganic compound and a plurality of quantum dots,
- the base material includes, as the inorganic compound, a base compound including at least one kind of first group VI element as a main component, and includes at least one kind of second group VI element having a smaller period number than the first group VI element included in the base compound, and
- a concentration of the sum of the second group VI elements in the base material is in a range from 1×1016 atoms/cm3 to 1×1020 atoms/cm3.
