Liquid droplet ejection apparatus, method for manufacturing electro-optic device, electro-optic device, and electronic equipement

摘要

A liquid droplet ejection apparatus performs a drawing operation on a workpiece set on a set table by driving the ejection of a functional liquid droplet ejection head in a head unit while moving the head unit in a main scanning direction relative to the set table. The liquid droplet ejection apparatus includes an ejection defect test unit for inspecting an ejection defect of the functional liquid droplet ejection head. The ejection defect test unit includes a drawn unit on which a predetermined test pattern is drawn by test ejection from the functional liquid droplet ejection head and ejection-defect determination means for determining the ejection defect by capturing an image of the test pattern drawn on the ejection-defect test unit and recognizing the image. The drawn unit is disposed on a scan moving axis offset from the set table towards the main scanning direction.
