Patent ID: 8752926

Claim:
A liquid ejecting apparatus comprising: a piezoelectric element provided with a piezoelectric layer and an electrode provided on the piezoelectric layer; and a driving unit supplying a driving waveform driving the piezoelectric element to the piezoelectric element, wherein the piezoelectric layer is formed of a composite oxide having a perovskite structure including bismuth, iron, barium and titanium, wherein the driving waveform has a waiting process of applying an intermediate potential to the piezoelectric layer, a first voltage changing process of applying a voltage of the opposite polarity to the intermediate potential from the application state of the intermediate potential, and decreasing the potential to the minimum, and a second voltage changing process of applying a voltage greater than the intermediate potential and ejecting a liquid, and increasing the potential to the maximum from the minimum potential, and wherein an electric field applied to the piezoelectric layer by the application of the intermediate potential is 11.1 V/μm or more, and is greater than half of a difference between the maximum potential and the minimum potential in the electric field applied to the piezoelectric layer.
