Abstract
There is disclosed an apparatus for spraying and patterning, using an electrostatic force, includes a nozzle to which a voltage is applied to exhaust ink, a droplet circulation chamber provided in one end of the nozzle, with a hole provided in one end to spray the ink exhausted from the nozzle based on a particle size of the droplet and to temporarily collect the not-sprayed ink, and a substrate for impacting the ink sprayed from the hole thereon by forming an electric field between the nozzle and the substrate.
