Abstract: The present disclosure relates to a method for preparing a conjugated polymer film, as well as a light-emitting diode, a display device, and a solar energy battery including the conjugated polymer film. A method for preparing a conjugated polymer film according to the present disclosure includes: preparing a fibrous conjugated polymer; and preparing a conjugated polymer film from the fibrous conjugated polymer. Since the fibrous conjugated polymer has a certain length and orientation, it has improved electron mobility in the dimensional direction thereof, and is capable of improving the carrier mobility of the conjugated polymer film.
