1. A method for manufacturing a display device, in which semiconductor light emitting diodes put into a chamber containing a fluid are seated at preset positions on a substrate including a first electrode and a second electrode spaced apart from each other with a dielectric layer disposed therebetween by using an electric field and a magnetic field, the method comprising:
applying a voltage to one of the first electrode and the second electrode to seat the semiconductor light emitting diodes at the preset positions on the substrate, respectively; and
after seating the semiconductor light emitting diodes at the preset positions, applying a voltage to the first electrode and the second electrode so that the semiconductor light emitting diodes seated at the preset positions are fixed to the preset positions, respectively.
