<p>Disclosed is a light-emitting device having a light-emitting layer composed of a monomolecular film of quantum dots, which is enhanced in luminance and luminous efficiency. Specifically disclosed is a light-emitting device (1) comprising at least an anode (3), a hole transporting light-emitting layer (5) composed of a hole transporting material and a quantum dot, an electron transporting layer (7) and a cathode (4) in this order. The hole mobility of the electron transporting layer (7) is lower than that of tris(8-quinolinolato)aluminum complex, and the hole transporting light-emitting layer (5) is so formed as to emit light when excitons generated in the electron transporting layer (7) are transferred into the light-emitting layer.</p> |
