Abstract: An apparatus of manufacturing a display device may include a reservoir that receives ink including a light emitting element and a solvent; an element-movement control module including a pipe part defining an ink channel fluidly connected to the reservoir, and an electrode part disposed on a surface of the pipe part; and a nozzle part that ejects the ink outward. The element-movement control module may operate in a first mode or a second mode. In case that the element-movement control module operates in the first mode, movement of the light emitting element may be unrestricted. In case that the element-movement control module operates in the second mode, the electrode part may form an electric field, and the movement of the light emitting element in the ink channel may be restricted at least in an area corresponding to a position at which the electrode part is disposed.
