Preparation method of light-emitting device, light-emitting device and light-emitting apparatus

Abstract

Disclosed are a preparation method of a light-emitting device, a light-emitting device, and a light-emitting apparatus. The light-emitting device includes a substrate, and a first electrode and a carrier assist layer that are arranged in stack on a side of the substrate, the first electrode is arranged adjacent to the substrate, and the preparation method includes: providing a substrate; forming the first electrode on a side of the substrate, the first electrode being provided with a patterned shape; by adopting an electrochemical polymerization method, placing the first electrode in an electrolyte solution as a positive electrode or a working electrode, and polymerizing polymerizable monomers in the electrolyte solution at the surface of the first electrode to form the carrier assist layer, where the material of the carrier assist layer includes a polymer of the polymerizable monomers.
