Abstract
A liquid droplet ejection apparatus includes a writing device, a weight measuring device disposed adjacent to the writing device, and a controlling device. The writing device performs writing on a workpiece by ejecting functional liquid from at least one ink jet functional liquid droplet ejection head while moving the functional liquid droplet ejection head relative to the workpiece. The weight measuring device measures an amount of ejected droplets from a weight of the functional liquid ejected from the functional liquid droplet ejection head. The controlling device controls a driving power for the functional liquid droplet ejection head on the basis of a measurement result input from the weight measuring device.
