Claim Text:
1. A liquid discharging substrate including a plurality of discharging units arrayed on the substrate having a first side and a second side opposite to the first side, comprising: a first pad configured to receive a first reference voltage, said first pad being arranged on the first side of the substrate; a second pad configured to receive a second reference voltage equal to the first reference voltage, said second pad being arranged on the second side of the substrate; a signal generating unit configured to generate a signal for driving the plurality of discharging units, said signal generating unit being arranged between said first pad and said second pad; a plurality of level shifters configured to shift a level of the signal from said signal generating unit and output the signal to the plurality of discharging units, said plurality of level shifters being arranged between said signal generating unit and said second pad; a first wiring line configured to supply the first reference voltage received by said first pad to said signal generating unit; and a second wiring line configured to supply the second reference voltage received by said second pad to said plurality of level shifters, wherein said first wiring line and said second wiring line are isolated from each other between said signal generating unit and said plurality of level shifters when viewed from an upper side with respect to an upper surface of the substrate.
