Abstract:
1. A coating method in which ink droplets containing functional material are ejected through nozzles on a substrate having a plurality of pixel regions having respective longitudinal axes parallel to each other and lyophobic portions adjacent to the respective pixel regions, to form a functional layer in each of the pixel regions, the method comprising: landing the ink droplets on a first pixel region and on first lyophobic portions at the same time, the first lyophobic portions being positioned in a direction of the longitudinal axis of the first pixel region and positioned adjacent to both lengthwise ends of the first pixel region, and the first lyophobic portions being positioned outside of the first pixel region; measuring a deviation of a landing position of the ink droplet on one of the first lyophobic portions from a set ink landing position which has been set in the first lyophobic portions, the set ink landing position being a relative position with respect to the first pixel region in a direction perpendicular to the longitudinal axis; and ejecting the ink droplets on a second pixel region and on second lyophobic portions of the substrate at the same time by correcting a timing of ink ejection through the nozzles based on the measured deviation, the second lyophobic portions being positioned in a direction of the longitudinal axis of the second pixel region and positioned adjacent to both lengthwise ends of the second pixel region, and the second lyophobic portions being positioned outside of the second pixel region.
