Abstract:
1. A liquid material drawing method for discharging droplets of a liquid material including a functional material from a plurality of nozzles to a plurality of pixel regions that are partitioned by barrier parts in a first direction and a second direction orthogonal to the first direction on a workpiece in synchronization with relative movement of the workpiece and the nozzles in the first direction to form pixel formation elements with one cycle of the relative movement including a forward movement and a reverse movement, the liquid material drawing method comprising: performing a first discharging step including observing and capturing an image of at least the first and second pixel regions in which the first and second droplets are discharged; computing distances in the first direction and distances in the second direction between the barrier parts and landing positions of the first and second droplets in the image of the at least the first and second pixel regions; correcting arrangement information including a relative positioning of the nozzles and the workpiece, which is used to arrange a prescribed number of the droplets as dots for each of the pixel regions, based on the distances in the first direction and the distances in the second direction; and performing a second discharging step in which the droplets are discharged based on the corrected arrangement information.
