Nanostructure network and method of fabricating the same

A method of fabricating a nanostructure network, the method comprising:

• preparing a nanostructure solution in which nanostructures are dispersed in a first solvent;
• forming a nanostructure ink by adding the nanostructure solution into a second solvent having a viscosity higher than that of the first solvent and an admixture for mixing the first solvent and the second solvent;
• coating a surface of a substrate with the nanostructure ink;
• and
• forming a nanostructure network by evaporating the first solvent and the second solvent included in the nanostructure ink coated on the substrate,
• wherein the coating of the surface of the substrate with the nanostructure ink comprises:
• generating a coating layer in a liquid state on the substrate;
• and
• dividing the coating layer into a plurality of first droplets spaced apart from each other, and
• wherein the forming of the nanostructure network comprises:
• evaporating the admixture prior to the first solvent and the second solvent from the first droplet to form a second droplet;
• evaporating the first solvent prior to the second solvent from the second droplet to form a third droplet;
• and
• evaporating the second solvent from the third droplet.
