Abstract
A driving circuit and a display device, to realize the drive circuit where settling time (stabilization time) is shortened, comprise power source lines for discharge (DCL1 through DCLJ). Each input node of a plurality of source amps (AMn) is electrically connected to the power source line for discharge (DCL1) during a first period and a second period in which a DAC circuit (2) supplies a gray scale reference voltage (V0 to V255) that has been selected to each of the plurality of source amps (AMn).
