Self-assembly donor and method for manufacturing display device using the same

A method for manufacturing a display device using a self-assembly donor, the method comprising:

• providing the self-assembly donor including:
• a self-assembly substrate;
• a first assembly electrode disposed on the self-assembly substrate;
• a second assembly electrode disposed on the self-assembly substrate and spaced apart from the first assembly electrode;
• an insulating layer covering the first assembly electrode and the second assembly electrode;
• a planarization layer disposed on the insulating layer and having a plurality of assembly pockets defined therein;
• and
• a plurality of via holes extending thorough the self-assembly substrate, the insulating layer, and the planarization layer;
• aligning each of light-emitting elements with one of the assembly pockets of the self-assembly donor so as to be received therein;
• providing a panel substrate including:
• an insulating layer having fluid channels defined therein, wherein each of the fluid channels vertically overlaps one of the plurality of via holes;
• and
• an adhesive layer on which one of the light-emitting elements is to be adhered;
• placing each of the panel substrate and the self-assembly donor into an attachment and detachment apparatus;
• moving and attaching the self-assembly donor having the light-emitting elements received in the assembly pockets to the panel substrate so that the light-emitting elements are adhered to the adhesive layer of the panel substrate;
• and
• performing a detachment process of removing the self-assembly donor from the panel substrate.
