Provided are an inkjet printing device, a method for printing bipolar elements, and a method for manufacturing a display device. The inkjet printing device comprises: a stage; an inkjet head disposed above the stage and including a plurality of nozzles through which an ink comprising bipolar elements each having partial regions doped with different polarities is discharged; an actuator disposed in the inkjet head to adjust the amount of droplets of the ink discharged through the nozzles; and at least one sensing unit disposed in the inkjet head to measure the number of the bipolar elements discharged through the nozzles.
