摘要： According to an aspect of the present disclosure, a liquid discharge head substrate includes a substrate having a parallelogram shape, a plurality of liquid discharge elements disposed on the substrate, a plurality of power supply terminals disposed along a first side of the substrate, and a first wiring, having a lattice shape, connected to the plurality of power supply terminals. On the substrate, the first side and a third side form an obtuse angle, and the first side and a fourth side form an acute angle. In the plurality of power supply terminals, the number of power supply terminals at positions closer to the third side than to the fourth side is larger than the number of power supply terminals at positions closer to the fourth side than to the third side.

摘要： A liquid discharge component includes discharge units arrayed to form columns each extending in a first direction and rows each extending in a second direction. Each discharge unit includes an element configured to apply energy to a liquid, and a driving circuit configured to drive the element. The component includes a logic circuit configured to control the driving circuit. The number of the columns is smaller than the number of the plurality of rows. The logic circuit includes shift registers configured to transfer, in the second direction, data to be supplied to the driving circuits. The shift register is configured to supply data to the discharge units of at least one row; the shift register includes flip-flops arranged in the second direction.
