Liquid discharge head, discharge device, and liquid discharge apparatus

Abstract

A liquid discharge head includes a nozzle plate, a channel plate, a common channel substrate, and a wall member. The nozzle plate includes a plurality of nozzles configured to discharge liquid. The channel plate includes a plurality of pressure chambers communicated with the nozzles, respectively. The common channel substrate includes a common channel communicated with the pressure chambers. The wall member includes a deformable region in a part of a wall surface of the common channel. The channel plate and the common channel substrate are disposed with the wall member interposed between the channel plate and the common channel substrate. The channel plate includes an air chamber facing the deformable region. The channel plate includes a bridge portion partially dividing the air chamber in a nozzle arrangement direction in which the nozzles are arranged. The bridge portion is not in contact with the wall member and the nozzle plate.
