Droplet ejection device and droplet ejection method

A droplet ejection device comprising:

• a first inspection unit configured to inspect a first droplet ejection unit including a plurality of electrostatic ejection type nozzles, the plurality of electrostatic ejection type nozzles configured to move in a first direction with respect to an object and ejecting a first droplet;
• a processor;
• and
• a memory device configured to store a program, the program being executed by the processor to cause the processor to:
• acquire information of the first droplet ejection unit;
• and
• set ejection conditions of the first droplet in each of the plurality of nozzles based on the acquired information of the first droplet ejection unit;
• a second inspection unit including an image sensor integrally equipped with the first droplet ejection unit, and configured to inspect an ejection result of the first droplet captured by the image sensor in response to the first droplet being ejected onto the object;
• and
• a second droplet ejection unit arranged away from the first droplet ejection unit and configured to eject a second droplet according to the inspected ejection result of the first droplet.
