Abstract
A droplet discharge device for discharging a liquid material onto a workpiece includes a droplet discharge head, a guide rail, a stage, a maintenance stage and a weight measurement device. The droplet discharge head discharges the liquid material. The guide rail extends in a prescribed direction. The stage, on which the workpiece is mounted, moves on the guide rail along the prescribed direction. The maintenance stage moves on the guide rail along the prescribed direction. The weight measurement device is disposed on the maintenance stage, the weight measurement device measuring weight of droplets discharged from the droplet discharge head and is able to be disposed at a location opposite the droplet discharge head when the maintenance stage moves along the guide rail.
