Abstract: There is provided a liquid discharge apparatus, including: a drive element configured to apply discharge energy to the liquid to discharge the liquid; signal generators configured to generate a plurality of types of drive signals having mutually different waveforms to drive the drive element; and drive switches electrically located between the signal generators and the drive element to correspond to the plurality of types of drive signals respectively. The drive switches include a first drive switch and a second drive switch which are different in ON-resistance.
