    Abstract: An inkjet printing apparatus may include a stage on which a substrate is seated; a nozzle part disposed above the stage and spraying an ink onto the substrate, the ink containing a solvent and solid substances; and a head part that supplies the ink to the nozzle part. The nozzle part includes an internal flow path extended in a first direction, through which the ink is supplied from the head prat; and an inlet in which an entrance area is defined. The ink is introduced in a second direction intersecting the first direction from the internal flow path through the entrance area. The inlet includes an inclined surface adjacent to the entrance area and defining the entrance area; and a flat surface parallel to the first direction. An angle between the inclined surface and the flat surface is an acute angle.

    Abstract: A display device includes: a substrate including a pixel area; and a pixel in the pixel area, the pixel including a first sub-light emitting area, a second sub-light emitting area, and a peripheral area surrounding the first and second sub-light emitting areas. The pixel may include: a first electrode, a second electrode, a third electrode, and a fourth electrode that are spaced from each other; a plurality of light emitting elements in the first and second sub-light emitting areas; a bank in the peripheral area and including a first opening corresponding to the first sub-light emitting area and a second opening corresponding to the second sub-light emitting area; and an intermediate bank between the first sub-light emitting area and the second sub-light emitting area and partially overlapping the second and third electrodes in a plan view.
