A droplet discharge device includes a stage, a droplet discharge head, a movement unit and a light radiating unit. The droplet discharge head includes nozzles arranged to discharge droplets of photo-curable liquid material toward a drawing region of a workpiece. The movement unit is arranged to move the stage and the droplet discharge head relative to each other. The light radiating unit has a light emitting part capable of emitting light to an entire area of the drawing region and disposed on a side opposite from the surface of the workpiece on which the liquid material is applied. The light emitting part is arranged not to emit the light to the portion of the drawing region when the droplet discharge head is disposed at a position over the portion, and to emit the light to the portion when the droplet discharge head has moved away from the position.
