FIELD: physics.
SUBSTANCE: disclosed is a method and an apparatus for droplet injection, capable of preventing development of a linear defect which is the result of operation of a defective nozzle from multiple nozzles of a jet head which injects a disproportionate droplet volume, which manifests itself as a visual defect when the image is displayed on a liquid crystal panel. When adjacent streams of the droplets of levelling material, which are formed as a result of movements in the direction Y of the jet head, are merged to form a levelling film on a substrate, the value of displacement in the direction X of the jet head is set such that adjacent streams are formed by different nozzles.
EFFECT: formation of adjacent streams of droplets injected from a defective nozzle can be prevented and then, areas of the levelling film having thickness which is less than that of other areas, which leads to linear defects, are not gathered together but are dispersed.
