description To suppress deterioration of printed image quality.SOLUTION: A liquid discharge device comprises: a plurality of discharge parts including a nozzle for discharging a liquid, a pressure chamber communicating with the nozzle, and a driving element; and a control part which controls supply of a driving signal to the driving element. The control part supplies a discharge driving signal, which includes a discharge waveform which discharges the liquid from the nozzle, to the driving element included in the discharge part, which discharges the liquid from the nozzle, of the plurality of discharge parts, as the driving signal, and supplies a non-discharge driving signal, which includes a non-discharge waveform which does not discharge the liquid from the nozzle, to the driving element included in the discharge part, which does not discharge the liquid from the nozzle, of the plurality of discharge parts, as the driving signal. The non-discharge waveform is so determined that a difference between a first value, which is obtained by time integration of a difference between a reference potential and a potential of the discharge driving signal in a range based on a driving period of the driving element, and a second value, which is obtained by time integration of the reference potential and a potential of the non-discharge driving signal in a range based on the driving period, falls within a prescribed range.SELECTED DRAWING: Figure 7 【課題】印刷される画像の質が低下することを抑制する。【解決手段】液体吐出装置は、液体を吐出するノズル、ノズルに連通する圧力室、及び、駆動素子を含む複数の吐出部と、駆動信号の駆動素子への供給を制御する制御部とを備え、制御部は、複数の吐出部のうちノズルから液体を吐出する吐出部に含まれる駆動素子に、ノズルから液体を吐出させる吐出波形を含む吐出駆動信号を駆動信号として供給し、複数の吐出部のうちノズルから液体を吐出しない吐出部に含まれる駆動素子に、ノズルから液体を吐出させない非吐出波形を含む非吐出駆動信号を駆動信号として供給し、非吐出波形は、駆動素子の駆動周期に基づく範囲で基準電位と吐出駆動信号の電位との差を時間積分することにより得られる第1の値と、駆動周期に基づく範囲で基準電位と非吐出駆動信号の電位との差を時間積分することにより得られる第2の値との差が、所定範囲に入るように、定められる。【選択図】図7
