Patent ID: 8353579

Claim:
A liquid ejecting head comprising: a channel member formed with a liquid channel having a plurality of ejection ports for ejecting droplets and a plurality of pressure chambers in fluid communication with respective ones of the plurality of ejection ports, the channel member having a surface formed with a plurality of openings through which respective ones of the plurality of pressure chambers are exposed; and an actuator including a layered body disposed on the surface of the channel member so as to confront the plurality of openings for applying energy to liquid in the plurality of pressure chambers, the layered body including a first piezoelectric layer and a second piezoelectric layer both sandwiched between electrodes with respect to a stacking direction, wherein the first piezoelectric layer is formed thereon with a plurality of independent electrodes separated from one another and arranged at positions corresponding to respective ones of the plurality of openings, the first piezoelectric layer having a plurality of independent active portions at positions where the plurality of independent electrodes is located, the plurality of independent active portions being capable of displacing selectively; wherein the second piezoelectric layer is formed thereon with a plurality of individual electrodes connected by connection electrodes and arranged at positions corresponding to the respective ones of the plurality of openings, the second piezoelectric layer having a plurality of individual active portions at positions where the plurality of individual electrodes is located, the plurality of individual active portions being incapable of displacing selectively; wherein each of the plurality of openings has a shape that is longer in one direction parallel to the surface than in another direction intersecting the one direction and parallel to the surface; wherein each of the plurality of individual electrodes has a shape that is longer in the one direction than in the another direction; and wherein the connection electrodes connect one-direction ends of the plurality of individual electrodes with one another, the one-direction ends being ends in the one direction.
