Abstract: Provided is a display device. The display device includes: a first display substrate; a second display substrate including a non-display region and first, second, and third pixel regions; and a sealing member overlapping the non-display region when viewed on a plane and between the first display substrate and the second display substrate. A dam pattern is arranged or a trench pattern is defined on a lower surface of the second display substrate. The dam pattern and the trench pattern control flow of a liquid organic material provided in the display region. An organic layer is formed only inside the dam pattern and the trench pattern so that a path into which moisture is introduced is not formed. This is because the organic layer is not on an outer region of a pattern on which the sealing member is located and the trench pattern.

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.
