DROPLET DISCHARGING DEVICE, METHOD OF MEASURING WEIGHT, METHOD OF DISCHARGING A LIQUID, AND METHOD OF MANUFACTURING A COLOR FILTER

摘要

A droplet discharging device is provided to properly measure weight of a liquid material discharged from plural discharge heads mounted on plural carriages. A droplet discharging device(1) for drawing by discharging a liquid material as droplets on a work(W) from a discharge head according to main scanning for relatively moving the work and the discharge head facing each other, includes: plural carriages(21) on which the plural discharge heads are mounted; a weight measurement unit(91) which measures weight of the discharged liquid material for every discharging head; and a main scanning moving unit which moves the weight measurement unit and the work each independently in a direction of the main scanning. The weight measurement unit is installed in a direction perpendicular to the direction of the main scanning along a drawing area(31) in which drawing and discharging is performed by the plural discharge heads mounted on the plural carriages.
