A liquid discharge head (11) includes a first actuator unit (40A) including a first nozzle substrate (20A) and a second actuator unit (40B) including a second nozzle substrate (20B). The first nozzle substrate (20A) has first nozzles in a first main portion of the first actuator unit (40A) and first overlapping nozzles in a first overlapping portion other than the first main portion. At least part of the first overlapping nozzles has a first overlapping diameter smaller than the first diameter. The second nozzle substrate (40B) has second nozzles in a second main portion of the second actuator unit (40B) and second overlapping nozzles in a second overlapping portion other than the second main portion. The second overlapping portion is overlapped with the first overlapping portion. At least part of the second overlapping nozzles has a second overlapping diameter larger than the first overlapping diameter.
