The present disclosure proposes a method for fabricating a graphene luminous component. The method includes: supplying a bottom substrate on which metallic gates are arranged at intervals; forming a first insulating protective layer covering the bottom substrate and the metallic gate; forming a graphene luminous layer with graphene luminous blocks on the first insulating protective layer; forming a graphene source and a graphene drain arranged at intervals on each of graphene luminous blocks; forming a second insulating protective layer covering the first insulating protective layer, the graphene luminous layer, the graphene source, and the graphene drain; and laminating a top substrate onto the second insulating protective layer. The present disclosure proposes a gate fabricated from metal, a source, a drain, and a luminous layer fabricated from graphene for the graphene luminous component. Therefore, the luminous efficiency of the luminous component is enhanced with lower power consumption.
