Abstract: An inkjet printing device includes a stage part including a stage, an inkjet head part including at least one inkjet head that disposes an ink on the stage, the ink including dipoles and a solvent having the dipoles, a heat treatment device that removes the solvent, a first sensing part that measures a position of the ink disposed on the stage, a second sensing part that measures a position of the inkjet head, and a third sensing part that measures a position of each of the dipoles disposed on the stage. A dipole aligning method includes disposing an ink on a substrate, the ink including dipoles and a solvent having the dipoles, generating an electric field on the substrate and disposing the dipoles on the substrate by the electric field, removing the solvent, and measuring a position of each of the dipoles disposed on the substrate.
