Claim:
1. A liquid discharge component including a plurality of discharge units arrayed to form a plurality of columns each extending in a first direction and a plurality of rows each extending in a second direction, wherein each of the plurality of discharge units includes a discharge orifice, a liquid chamber communicating with the discharge orifice, an element configured to apply energy to a liquid in the liquid chamber, and a driving circuit configured to drive the element, the liquid discharge component comprises a logic circuit configured to control the driving circuits of the plurality of discharge units, the number of the plurality of columns is less than the number of the plurality of rows, the logic circuit includes a plurality of shift registers configured to transfer, in the second direction, data to be supplied to the driving circuits of the plurality of discharge units, each shift register is configured to supply data to the discharge units of at least one row, each shift register includes a plurality of flip-flops arranged in the second direction in correspondence with the plurality of columns and connected in series, each of the plurality of flip-flops supplies data to the driving circuit of the discharge unit that is included in the at least one row corresponding to the shift register including the flip-flop, and included in a column corresponding to the flip-flop, the liquid chamber of each of the discharge units forming one column out of the plurality of discharge units communicates with a supply port configured to supply a liquid, the supply port includes a first portion extending in the first direction, a plurality of second portions configured to make the first portion communicate with the liquid chamber of each of the discharge units forming one column out of the plurality of discharge units, and beams provided between the second portions adjacent to each other among the plurality of second portions, and at least one of the shift registers transfers data through a wiring pattern provided on one of the beams.
