1. A method of manufacturing a display device, the method comprising:
introducing an ink base material and ink comprising first ink particles and second ink particles into an inner passage of a surface acoustic wave module;
separating the first ink particles having an average particle diameter equal to or greater than a first particle diameter from the second ink particles having an average particle diameter smaller than the first particle diameter based on the first particle diameter utilizing a surface acoustic wave of a surface acoustic wave generator around the inner passage; and
spraying an ink mixture of the separated second ink particles and the ink base material onto a substrate,
wherein the introducing the ink base material and the ink into the inner passage comprises introducing the ink base material and the ink into the inner passage through respective inflow passages.
