Claim Text:
1. A semiconductor device for a liquid discharge head, comprising: a first electrode configured to supply a first voltage; a second electrode configured to supply a second voltage different from the first voltage; a plurality of discharge elements configured to impart energy to a liquid, each discharge element including a first terminal and a second terminal; a plurality of first switching elements configured to electrically connect the first terminals of the plurality of discharge elements to the first electrode, and including one or more first switching elements each connected to two or more discharge elements among the plurality of discharge elements; and a plurality of second switching elements configured to electrically connect the second terminals of the plurality of discharge elements to the second electrode, and including one or more second switching element each connected to two or more discharge elements among the plurality of discharge elements, wherein two or more discharge elements connected to a same second switching element, among the plurality of discharge elements are connected to different first switching elements among the plurality of first switching elements, wherein the number of the plurality of first switching elements is smaller than that of the plurality of second switching elements, wherein the plurality of discharge elements are arranged in a direction, wherein the plurality of first switching elements are arranged in the direction, and wherein the plurality of second switching elements are arranged in the direction.
