1. A liquid discharge head comprising:
a plurality of nozzles aligned on a nozzle surface;
a supply manifold arranged apart from the nozzle surface in a first direction orthogonal to the nozzle surface, and configured that a liquid is supplied therein from the outside of the liquid discharge head;
a return manifold which is arranged between the nozzle surface and the supply manifold in the first direction, which is configured that the liquid is flown out therefrom to the outside of the liquid discharge head, and which is provided with a return damper part; and
a plurality of individual flow channels each of which corresponds to one of the plurality of nozzles, and each of which has one end connected to the supply manifold and the other end connected to the return manifold,
wherein each of the plurality of individual flow channels has a return throttle channel communicating the corresponding nozzle with the return manifold and being arranged between the return manifold and the nozzle surface in the first direction, and
the return manifold has a compliance larger than a compliance of the supply manifold.
