Liquid discharge apparatus and method of driving liquid discharge head

A liquid discharge apparatus comprising:

• a diaphragm that has a first surface and a second surface facing in a direction opposite to the first surface;
• a pressure chamber substrate laminated on the first surface and including a partition wall partitioning a pressure chamber communicating with a nozzle discharging liquid;
• a piezoelectric element laminated on the second surface and including a first active portion that overlaps a center of the pressure chamber when viewed in a thickness direction of the diaphragm and a second active portion that overlaps the pressure chamber at a position closer to an outer edge of the pressure chamber than the first active portion;
• and
• a drive signal generation portion that generates a discharge signal for discharging the liquid from the nozzle by being supplied to one of the first active portion and the second active portion and a correction signal that is supplied to the other of the first active portion and the second active portion, wherein
• a potential of the discharge signal changes over time and a potential of the correction signal is constant during a discharge period for discharging the liquid from the nozzle.
