Abstract
The display device includes a substrate, a plurality of light-emitting elements including a quantum dot layer including a plurality of quantum dots and a first inorganic material with which spaces between the plurality of quantum dots are filled, and an inorganic layer. The inorganic layer is located between the at least two light-emitting elements. Furthermore, the inorganic layer contains a second inorganic material including a semiconductor having a band gap of 2.8 eV or more or an insulator.
