Liquid discharge head, liquid discharge unit, and liquid discharge apparatus

A liquid discharge head comprising:

• a first actuator unit including a first nozzle substrate arranged in a first direction;
• and
• a second actuator unit including a second nozzle substrate arranged in the first direction,
• wherein the first nozzle substrate has:
• first nozzles in a first main portion of the first actuator unit, each of the first nozzles having a first diameter;
• and
• first overlapping nozzles in a first overlapping portion of the first actuator unit other than the first main portion,
• at least part of the first overlapping nozzles having a first overlapping diameter smaller than the first diameter, and
• the second nozzle substrate has:
• second nozzles in a second main portion of the second actuator unit, each of the second nozzles having a second diameter;
• and
• second overlapping nozzles in a second overlapping portion of the second actuator unit other than the second main portion,
• the second overlapping portion overlapped with the first overlapping portion in a second direction orthogonal to the first direction, and
• at least part of the second overlapping nozzles having a second overlapping diameter larger than the first overlapping diameter.
