Droplet discharge device, method of discharging droplet, method of manufacturing electro-optical device, electro-optical device and electro equipment

A method of discharging a droplet in which the droplet is discharged from a head to a workpiece, comprising:

• sealing a surface of a nozzle by a device that is capable of sealing and suctioning the surface of the nozzle;
• discharging the droplet from the nozzle to the device capable of sealing and suctioning;
• controlling a suction operation and a flushing operation such that during the suction operation, the device capable of sealing and suctioning seals and suctions the surface of the nozzle, and during the flushing operation the surface of the nozzle is left sealed and the head discharges at least one droplet from the nozzle such that the surface of the nozzle is left moist, wherein the flushing operation is performed when a number of clogged nozzles exceeds a predetermined number;
• and
• selecting at least one of the suction operation and the flushing operation.
