PROBLEM TO BE SOLVED: To provide a droplet discharge device capable of forming a uniform thin film while suppressing variation in droplet discharge quantity due to the change of a discharge pattern. SOLUTION: The droplet discharge device IJ is provided with: a droplet discharge head 5 having a plurality of nozzles and a driving device PZ provided corresponding to each nozzle; and a drive waveform storing means 100 for storing waveform data of a drive signal supplied to each drive device PZ. The drive voltage, the drive frequency or the drive waveform of the drive signal is set corresponding to the discharge pattern which is a combination of the use nozzle and the nonuse nozzle in the droplet discharge head 5 and the drive waveform storing means 100 stores the drive voltage, the drive frequency or the waveform data corresponding to the discharge pattern in every discharge pattern.
