Claim 16:
17. A method of fabricating a display device that uses a printing apparatus comprising a storage unit accommodating a material in which at least one light emitting element is dispersed, and a print head unit that sprays a material supplied from the storage unit, the method comprising:
preparing a substrate comprising a first pixel electrode and a second pixel electrode spaced apart from each other;
spraying the material onto the substrate through the print head unit; and
aligning the at least one light emitting element of the material between the first pixel electrode and the second pixel electrode,
wherein the material is a fluid solvent and an ink in which the at least one light emitting element is dispersed in the solvent, and further comprising:
applying a power source to a first electrode and a second electrode spaced apart from each other in the storage container of the storage unit, wherein an electric field is formed between the first electrode and the second electrode, so that the material is stirred by electroosmosis, and the light emitting element is maintained in a floating state in the storage container.
