Light-emitting device and method for manufacturing light-emitting device

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.
