Light-emitting element

Abstract

A light-emitting element includes: an anode and a cathode; a light-emitting layer positioned between the anode and the cathode, the light-emitting layer including a plurality of quantum dots and an inorganic matrix material with which spaces between the plurality of quantum dots are filled; and at least either (i) an electron transport layer positioned between the light-emitting layer and the cathode and a first auxiliary layer being in contact with the light-emitting layer on a cathode side, the first auxiliary layer being made of a material different from the inorganic matrix material or (ii) a hole transport layer positioned between the anode and the light-emitting layer and a second auxiliary layer being in contact with the light-emitting layer on an anode side, the second auxiliary layer being made of a material different from the inorganic matrix material.
