Abstract: An inkjet spraying method includes preparing a spraying unit including nozzles for spraying an organic material on a target substrate including first pixels which display a same color, spraying the organic material to each of first pixels of a (1+a×n)th first-pixel row in the first pixels, and spraying the organic material to each of first pixels of a (2+a×n)th first-pixel row in the first pixels, where a first nozzle in the nozzles sprays the organic material to a first reference pixel in the first pixels of the (1+a×n)th first-pixel row, a second nozzle, which is different from the first nozzle, in the nozzles sprays the organic material to a second reference pixel in the first pixels of the (2+a×n)th first-pixel row, and the second reference pixel is disposed in parallel with the first reference pixel in a column direction.
