Abstract
A light-emitting element includes, in sequence, an anode, a hole transport layer, a luminous layer containing a plurality of quantum dots, an electron transport layer, and a cathode. The electron transport layer includes a plurality of inorganic nanoparticles having electron transportability, and an organic layer having electron transportability. The organic layer partly contains the plurality of inorganic nanoparticles, and includes a plurality of first hollows in an interface adjacent to the luminous layer. The plurality of first hollows are filled with the plurality of quantum dots.
