Disclosed are a quantum dot display device and a manufacture method thereof. The quantum dot display device includes a flexible substrate, a first electrode layer, a second electrode layer, and a component combination layer. The material of the first electrode layer is a fullerene-graphene material or a carbon nanotube-graphene material. The material of the second electrode layer is the carbon nanotube-graphene material or the fullerene-graphene material. Or else, both of the material of the first electrode layer and the material of the second electrode layer are non-metal doped graphene. The device can reduce a use of metal material and thus avoid damage to the environment.
