Abstract:
A liquid ejection head including: an insulating nozzle plate 5 provided with a nozzle having, a liquid supply port to supply liquid and a ejection port to eject the liquid supplied from the liquid supply port onto a substrate; a cavity in communication with the liquid supply port to reserve the liquid to be ejected from the ejection port; an electrostatic voltage application device to generate an electrostatic attraction force by applying the electrostatic voltage between the liquid in the nozzle and in the cavity, and substrate; and a control device to control application of the electrostatic voltage through the electrostatic voltage application device; wherein the nozzle is a flat nozzle not protruding from the nozzle plate and the control device control the electrostatic voltage application device so as to eject the liquid from the nozzle by applying a bipolar pulse which alternates between negative and positive polarity.
