Beschreibung
Zusammenfassung:	A liquid ejection head includes a first piezoelectric element that is supplied with a first drive signal, and a second piezoelectric element that is supplied with a second drive signal, wherein the first drive signal transitions from a first potential to a second potential in a first period, maintains the second potential during a second period, and transitions from the second potential to the first potential in a third period, wherein the second drive signal transitions from a third potential to a fourth potential in a fourth period, maintains the fourth potential during a fifth period, and transitions from the fourth potential to the third potential in a sixth period, wherein the first period and the fourth period overlap, wherein the third period and the sixth period overlap, wherein the second potential is higher than the first potential, and wherein the fourth potential is lower than the third potential.
