Abstract
The present invention is directed at a liquid discharge device having reduced crosstalk, which slows the rate of change of liquid discharge speed, and is suitable as a printing head. The liquid discharge device includes a piezoelectric actuator and a flow passage member. The piezoelectric actuator has a plurality of driving electrodes from on a piezoelectric ceramic layer, and a plurality of piezoelectric displacement elements is disposed longitudinally and laterally with regularity. In the flow passage member, a plurality of liquid compressing chambers is formed with liquid outlet orifices. The piezoelectric actuator is placed on the flow passages member, so that the driving electrodes correspond in position to the liquid compressing chambers.
