Liquid discharging apparatus and circuit substrate

A liquid discharging apparatus comprising:

• a discharging unit that includes a driving element and discharges a liquid by driving of the driving element;
• and
• a circuit substrate that transmits a first drive signal to drive the driving element and a control signal to control application of the first drive signal to the driving element,
• wherein the circuit substrate includes
• a receiving unit that receives a transmission signal based on a plurality of original control signals and restores the plurality of control signals based on the transmission signal,
• first wiring that transmits the transmission signal,
• second wiring that transmits the control signals,
• third wiring that transmits the first drive signal,
• fourth wiring that transmits a reference voltage signal to supply a reference voltage, which is applied to the other end of the driving element different from one end of the driving element, to which the first drive signal is applied, and
• a first input terminal that is connected to the first wiring and inputs the transmission signal into the circuit substrate,
• the receiving unit is connected to the first wiring and the second wiring,
• the receiving unit, the first wiring, and the first input terminal are provided on a first layer of the circuit substrate,
• the third wiring is provided on a second layer different from the first layer,
• the fourth wiring is provided on a fifth layer that is different from the first layer and the second layer, and
• the fourth wiring and the third wiring are provided so as to have at least a part where the fourth wiring and the third wiring overlap in planar view of the circuit substrate.
