A liquid ejecting apparatus includes 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, in which the piezoelectric layer is formed of a composite oxide having a perovskite structure including bismuth, iron, barium and titanium, in which 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 in which 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. |
