Abstract

See full text

Provided is a liquid ejecting apparatus which comprises a pressure generation chamber, a piezoelectric element, and a driving unit which supplies a driving signal to the piezoelectric element. The piezoelectric layer shows electric field induced phase transition and when among voltages at which the piezoelectric layer shows the electric field induced phase transition a voltage having a higher absolute value is defined as VF and a voltage having a lower absolute value is defined as VAF, the driving unit supplies to the piezoelectric element a driving signal which allows the voltage to be applied to the piezoelectric layer, allows the voltage that passes through VF and of which the absolute value is equal to or higher than VAF to be set as a start point, and allows the voltage to be changed within a range where the absolute value is equal to or higher than VAF.
