Abstract
An apparatus for manufacturing a display device, the apparatus comprising: a droplet discharger comprising a nozzle configured to discharge a droplet; a first detector on a falling path of the droplet that falls from the droplet discharger and configured to detect a shape of the droplet; a second detector spaced apart from the first detector and configured to detect the shape of the droplet that falls from the droplet discharger; and a controller configured to calculate at least one of a volume of the droplet, a falling speed of the droplet, the falling path of the droplet, or a discharge angle, at which the droplet is discharged from the nozzle, based on results detected by the first detector and the second detector.
