Self-assembly device

A self-assembly apparatus comprising:

• a chamber;
• at least one first supply part configured to supply a fluid to the chamber;
• a mounting part disposed on a first side of the chamber to mount a substrate to be inclined with respect to a horizontal plane of the chamber, the substrate having an assembly surface;
• a collection part on a lower side of the chamber;
• a collection induction part disposed between the lower side of the chamber and the collection part;
• and
• a magnet module disposed on an opposite surface of the substrate opposite to the assembly surface of the substrate,
• wherein the mounting part is configured to:
• insert the substrate into an upper side of the chamber,
• guide the inserted substrate from the upper side of the chamber toward the lower side of the chamber, and
• fix the guided substrate to the lower side of the chamber.

A self-assembly apparatus, comprising:

• a chamber having a first side and a second side facing the first side;
• at least one first supply part at the second side of the chamber, and configured to supply a fluid into the chamber;
• at least one second supply part at the second side of the chamber, and configured to supply a plurality of light emitting devices to the chamber;
• a collection part on a lower side of the chamber;
• an assembly substrate at the first side of the chamber, and having an assembly surface configured to receive the plurality of light emitting devices;
• and
• a magnet module adjacent to the substrate at a location outside of the chamber.
