Abstract
Discussed is a method of manufacturing a display device, the method including: introducing semiconductor light emitting devices including a magnetic material into a fluid chamber; transferring a substrate to the fluid chamber, the substrate including assembly electrodes, an insulating layer covering the assembly electrodes, and open holes in the insulating layer and exposing portions of both ends of the assembly electrodes; applying a magnetic force to the semiconductor light emitting devices introduced into the fluid chamber to move the semiconductor light emitting devices in one direction; and forming an electric field so that the moving semiconductor light emitting devices are disposed at preset positions of the substrate, wherein a probe pin is in contact with the assembly electrodes exposed through the open holes to individually apply a voltage to the assembly electrodes to form the electric field.
