Abstract
A liquid discharge head of the invention includes a drive substrate, a flexible wiring substrate mounted in a standing state with respect to the drive substrate, and a semiconductor device which is mounted on the flexible wiring substrate and which has a pair of long sides in a direction crossing a direction in which the flexible wiring substrate stands. A plurality of output electrodes respectively electrically connected to the electrodes of the drive substrate are arranged on and along the long side of the semiconductor device facing the drive substrate. A plurality of input electrodes are arranged on and along the long side opposite to the long side of the semiconductor device facing the drive substrate. A circuit that drives the drive element is provided in a region between two certain input electrodes of the semiconductor device.
