发明名称 LIQUID EJECTING HEAD, LIQUID EJECTING APPARATUS, AND ACTUATOR UNIT
摘要 A liquid ejecting head includes a flow channel-forming substrate including a pressure-generating chamber that is in communication with a nozzle opening through which liquid is ejected; and a piezoelectric device that is provided on a surface of the flow channel-forming substrate and is configured to cause change in pressure of the pressure-generating chamber. The piezoelectric device includes a pair of electrodes constituted by a cathode and an anode, and a piezoelectric layer that is sandwiched between the pair of electrodes and is displaceably disposed. A negatively charged region is formed in a portion of the piezoelectric layer, the portion being near the cathode. A positively charged region is formed in a portion of the piezoelectric layer, the portion being near the anode.
