摘要： A droplet discharge device includes: a head driven to discharge a functional liquid as a droplet; a driving voltage generation unit that generates a driving voltage to drive the head; a first temperature acquisition unit to acquire a temperature of the functional liquid in the head as a first temperature in a case where the head is in a head waiting state in which the head is waited; a second temperature acquisition unit to acquire a temperature of the functional liquid in the head as a second temperature in a case where the head is in a head driven state in which the head is driven; a temperature difference computing unit that computes a temperature difference between the first temperature and the second temperature; and a driving voltage correction unit that corrects the driving voltage based on the temperature difference. The driving voltage generation unit generates the corrected driving voltage to the head in a case where the head is in the head driven state.
