Abstract: A light-emitting device that includes an anode, a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and a cathode on a transparent substrate. The light-emitting layer has a plurality of quantum dots dispersed therein, and a hole-transporting material is dispersed in gaps between the quantum dots. To for manufacturing the light-emitting device, a quantum dot dispersing solution having the quantum dots dispersed therein, and a hole-transporting solution containing a soluble hole-transporting material that is soluble in the quantum dot dispersing solution and has a hole transport property are prepared. The hole-transporting solution is applied onto the hole injection layer to form a hole-transporting coating film, and the quantum dot dispersing solution is then applied onto the hole-transporting coating film to dissolve the soluble hole-transporting material in the quantum dot dispersing solution.

Abstract: A light-emitting element where a positive electrode is formed on the surface of a transparent substrate; a hole transport layer is formed on the surface of the positive electrode; and a light-emitting layer made of quantum dots is formed on the surface of the hole transport layer. The light-emitting layer has a light-emitting region that emits light of a first predetermined wavelength in which a surfactant is present on the surface of the quantum dots and a non-light-emitting region that does not emit light in which a surfactant is absent on the surface of the quantum dots. A second light-emitting layer that emits light of a second predetermined wavelength is formed on the surface of the light-emitting layer, and a negative electrode is formed on the surface of the second light-emitting layer.
