Inkjet printing apparatus, dipole alignment method, and display device manufacturing method

An inkjet printing apparatus, a dipole alignment method, and a display device manufacturing method are provided. The inkjet printing apparatus includes a stage, a print head part disposed above the stage, and an electric field generating part that provides an electric field to a space between the stage and the print head part. The dipole alignment method includes providing an electric field at an area above a target substrate, spraying ink including a dipole onto the target substrate through the area, and landing the dipole on the target substrate. The display device manufacturing method includes preparing a base layer on which first and second electrodes are disposed, spraying ink including a light emitting element onto the base layer through the area, landing the light emitting element between the first and second electrodes.
