LIQUID DISCHARGE HEAD, LIQUID DISCHARGE DEVICE, AND LIQUID DISCHARGE APPARATUS

摘要

A liquid discharge head includes a plurality of nozzles, a plurality of individual liquid chambers, a common liquid chamber, a common circulation liquid chamber, and a filter portion. The common liquid chamber includes a first portion disposed side by side with the common circulation liquid chamber in a direction perpendicular to a nozzle array direction in and a second portion not disposed side by side with the common circulation liquid chamber in the direction perpendicular to the nozzle array direction. In a plan view, the second portion partially overlaps the common circulation liquid chamber in the direction perpendicular to the nozzle array direction. A width of the second portion in the direction perpendicular to the nozzle array direction is greater than a width of the first portion in the direction perpendicular to the nozzle array direction. In the plan view, the filter portion is disposed in the second portion.
