A liquid discharge apparatus includes a nozzle plate with nozzles and actuators and a drive controller. First and second nozzles are directly adjacent to each other in a first direction. First and third nozzles are directly adjacent to each other in a second direction. The drive controller is configured to apply a drive signal to first, second, and third actuators corresponding to the first, second, and third nozzles, respectively, during a drive cycle. A difference between a first timing at which the drive signal is applied to the first actuator and a second timing at which the drive signal is applied to the second actuator and a difference between the first timing and a third timing at which the drive signal is applied to the third actuator is an odd number multiple of a half of an inherent vibration cycle of the liquid discharge apparatus.
