摘要:
An inkjet printing device includes a flow path plate comprising a manifold to supply ink, a pressure chamber filled with the ink supplied from the manifold, and a nozzle via which the ink is ejected, a piezoelectric actuator which is disposed on a top surface of the flow path plate and includes a lower electrode, a piezoelectric layer, and an upper electrode that are stacked sequentially, a first electrostatic electrode to generate an electrostatic field, and a second electrostatic electrode which is disposed a predetermined distance apart from a bottom surface of the flow path plate to generate the electrostatic field between the first electrostatic electrode and the second electrostatic electrode.
