A method of manufacturing a flexible conductive wire, a flexible conductive wire, and a display device are provided. The method manufacturing the flexible conductive wire includes: forming a zinc oxide nano-monomer into a patterned substrate, coating a carboxylated silver/3,4-ethylenedioxythiophene: polystyrenesulfonic acid solution on the patterned substrate, and curing the patterned substrate and the carboxylated silver/3,4-ethylenedioxythiophene: polystyrenesulfonic acid solution to form a flexible conductive wire. Display performance of a display panel can be improved.
