Abstract
A self-assembly apparatus can include a fluid chamber for accommodating a fluid and semiconductor light-emitting elements, a conveyor to convey an assembly substrate so one surface of the assembly substrate is immersed in the fluid, the assembly substrate having a plurality of assembly electrodes, a magnet array spaced apart from the fluid chamber to apply a magnetic force to the semiconductor light-emitting elements, a power supply to apply power to the plurality of assembly electrodes disposed on the assembly substrate so that the semiconductor light-emitting elements are seated in a preset region on the assembly substrate, and a repair substrate disposed to face the one surface of the assembly substrate and including a plurality of pair electrodes on which an electric field is generated as power is supplied. The plurality of pair electrodes can be disposed at the same interval as the plurality of assembly electrodes.
