Abstract
A liquid ejecting head includes a first-nozzle-row set in which a pair of first-nozzle-rows is disposed in a second direction intersecting a first direction so that the first-nozzle-rows are symmetrical about a reference line extending in the first direction and a second-nozzle-row set in which a pair of second-nozzle-rows is disposed in the second direction so that the second-nozzle-rows are symmetrical about the reference line. In the second direction, the distance between the second-nozzle-rows is longer than the distance between the first-nozzle-rows. First nozzles constituting the first-nozzle-row set communicate with a first liquid supply source via a first supply flow path. Second nozzles constituting the second-nozzle-row set communicate with a second liquid supply source via a second supply flow path. Compliance capacity of the second supply flow path is larger than compliance capacity of the first supply flow path.
