Abstract
An apparatus for manufacturing a display device includes: a stage configured to hold a substrate; a movement unit configured to move relative to the stage; a head unit arranged on the movement unit and including a nozzle for discharging a liquid droplet onto the substrate; and a sensor unit configured to emit a laser to irradiate the liquid droplet falling from the head unit to the substrate to sense a portion of a planar shape of the liquid droplet. The apparatus is configured to control the movement unit or the head unit based on the sensed portion of the planar shape.
