| titleOfInvention | Liquid ejector |
| abstract | A liquid ejecting apparatus capable of obtaining sufficient displacement characteristics by using a composite oxide having a perovskite structure containing bismuth, iron, barium, and titanium as a piezoelectric material. A liquid ejecting apparatus including a piezoelectric element including a piezoelectric layer and an electrode, and a driving unit that drives the piezoelectric element, wherein the piezoelectric layer is preferentially oriented in a (110) plane, The driving waveform is composed of a polarization step in which a first voltage equal to or higher than the coercive voltage of the piezoelectric layer is applied to be in a polarization state, and a first waveform to a first voltage from the first voltage to the first voltage. A voltage having a polarity opposite to that of the voltage is applied to relax the polarization of the piezoelectric layer and the voltage is lowered to the minimum potential, and from the minimum potential, a voltage higher than the first voltage is applied to discharge the liquid. And a second voltage changing step for raising the voltage to the maximum potential, and the difference in electric field applied to the piezoelectric layer between the maximum potential and the minimum potential is 6.1 × 10 7 (V / m) or less.
