▎ 摘　　要

NOVELTY - The device has a quantum dot light-emitting layer provided with a graphene layer. A quantum dot is formed within multiple nano holes. A hole-transport layer is formed on the quantum dot light-emitting layer. The graphene layer is made of multiple graphene sheets. An electron-transport layer is provided with metal oxide, silicon nitride, titanium dioxide, zirconium dioxide and hafnium oxide. USE - Quantum dot light emitting device. ADVANTAGE - The device increases quantum efficiency, controls surface density of the quantum dot and improves light efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a quantum dot light emitting device manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a quantum dot light emitting device.
