1. A method of fabricating a light-emitting device, comprising:
forming a light-emitting structure layer on one side of a substrate, the light-emitting structure layer comprising a light-emitting function layer;
forming a first light extraction layer on a light exit side of the light-emitting function layer;
performing plasma treatment on a light exit surface of the first light extraction layer to form an irregular brush micro-nano structure; and
forming a light extraction mesh film on the light exit side of the light-emitting function layer, wherein the light extraction mesh film has a sponge pore structure, wherein the forming the light extraction mesh film comprises:
uniformly mixing raw materials for forming the light extraction mesh film to obtain a first mixture;
after the first mixture is sprayed into a film, curing the film with ultraviolet radiation to obtain a cured film layer; and
removing a liquid crystal in the cured film layer to obtain the light extraction mesh film,
wherein the raw materials comprise a monomer, a liquid crystal, a photoinitiator, and nano microbeads, or the raw materials comprise a monomer, a liquid crystal, a photoinitiator, scattering particles, and nano microbeads.
