▎ 摘　　要

NOVELTY - The device has a device combination layer (103) which comprises an electron transport layer and carbon quantum dot light emitting layer, a hole transport layer and a hole injection layer. The material corresponding to the first electrode layer (102) is fullerene-graphene and carbon nanotubes are made of graphene. The material corresponding to the second electrode layer (104) is fullerene-graphene. The material corresponding to the first electrode layer and the material corresponding to the second electrode layer are non-metallic doped graphene. USE - Quantum dot display device. ADVANTAGE - The quantum dot display device reduces the use of metal material and avoids damaging the environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method of quantum dot display device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the quantum dot display device.
