Liquid material drawing method, color filter manufacturing method, and organic EL element manufacturing method

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
• discharging a first droplet among the droplets from a first nozzle among the nozzles into a first pixel region among the pixel regions during the forward movement of the relative movement, and
• discharging a second droplet among the droplets from a second nozzle among the nozzles into a second pixel region among the pixel regions during the reverse movement of the relative movement, the second pixel region being aligned with the first pixel region in the second direction,
• two most distant nozzles among the nozzles corresponding to the first pixel region and the nozzles corresponding to the second pixel region being selected as the first and second nozzles;
• 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.
