Abstract:
1. A liquid discharging device comprising: a first substrate comprising a first surface having a plurality of energy generators for generating energy for discharging a liquid, and a second surface having a plurality of liquid supply openings arranged on the opposite side of said first surface, each supply opening corresponding to one of a plurality of first penetrating holes of the first substrate; a nozzle member provided on said first surface side of said first substrate and having a plurality of liquid discharge nozzles; and a second substrate laminated on said second surface side of said first substrate and having a plurality of second penetrating holes which continue through the second substrate, wherein each one of said plurality of second penetrating holes is in communication with a supply opening of a corresponding one of said plurality of first penetrating holes, to form a plurality of individual flow paths that are independent from one another, each flow path comprising a single second penetrating hole, a single first penetrating hole, a single nozzle, and a single channel that communicates with the nozzle and the first penetrating hole, wherein a position of the nozzle is not aligned with a position of the first penetrating hole, and wherein each energy generator of the plurality of energy generators is positioned adjacent to a corresponding channel and a corresponding nozzle.
