[Object] To realize a drive circuit where settling time (stabilization time) is shortened, without incurring marked increase in electric current consumed and marked increase in manufacturing costs. [Solution] A source drive circuit () has a digital gradient input converter () that converts gradient values of multiple image data (Dthrough Dn) that are gradientinto multiple gradient values, where the number of the multiple source amps (AMthrough AMn) to which a gradient reference voltage (V) corresponding to gradientis supplied, is reduced, and supplied to a DAC circuit ().
