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.
