PROBLEM TO BE SOLVED: To provide: a liquid drop discharge device, restraining deterioration of image quality by making uneven ribbing inconspicuous, and having excellent production efficiency; a liquid drop discharge method; and a method of manufacturing a color filter. SOLUTION: This liquid drop discharge device includes: a liquid drop discharge head 5 having a plurality of nozzles for discharging a functional liquid and a plurality of driving elements; a supply reel 12 for supplying a sheet member 15; a take-up reel 13; an imaging device 14 for imaging an image of a functional liquid; an analyzing means 32 for obtaining a distribution of discharge amount of the functional liquid; and a control means 31 for adjusting the voltage applied to the plurality of driving elements so that the discharge amount in the plurality of nozzles approaches a predetermined proper amount from the distribution. The control means 31 calculates a discharge number Ns of the functional liquid to be discharged from the respective nozzles based on the following expression (1). Expression (1): Ns=äσ×Z(α/2)/E}<SP>2</SP>. In the expression, when reliability rate in a normal distribution where a predetermined expectation value and a standard deviation areσisα, a probability variable is Z(α/2), and a predetermined error amount is E.
