PROBLEM TO BE SOLVED: To provide an electrostatic suction-type liquid discharge device, which can reduce effectively a deviation of an impact position from a desired position, with a simple configuration.SOLUTION: A liquid discharge device 100 comprises: a liquid discharge head 101 including a plurality of parallely arranged electrodes; an opposing electrode 102 arranged at a position opposing to the liquid discharge head 101; and a control portion 501 that controls voltages to be applied to the electrodes so that the plurality of electrodes respectively are driven as a discharging electrode by which liquid is discharged or a non-discharging electrode by which liquid is not discharged. The control portion 501 adjusts values of the voltages to be applied to the electrode to be driven as the non-discharging electrode, on the basis of voltages to be applied to an electrode adjacent to the non-discharging electrode.SELECTED DRAWING: Figure 1 【課題】静電吸引式の液体吐出装置において、単純な構成で所望の位置からの着弾位置のずれを効果的に低減させることが可能な液体吐出装置を提供する。【解決手段】液体吐出装置１００は、並設された複数の電極を含む液体吐出ヘッド１０１と、液体吐出ヘッド１０１と対向する位置に設けられた対向電極１０２と、電極に印加する電圧を制御して、複数の電極のそれぞれを、液体を吐出させる吐出用電極または液体を吐出させない非吐出用電極として駆動する制御部５０１と、を備え、制御部５０１は、非吐出用電極として駆動する電極に印加する電圧の値を、当該電極に隣接する電極に印加する電圧に基づいて調整する。【選択図】図１
