1. A source driver, of a liquid crystal display device, comprising:

  • a plurality of output buffers to drive source lines;

    a voltage sharing unit to share voltage levels on the source lines during a charge-sharing interval; and

    a controller configured to generate a slew-rate control signal in response to the charge-sharing interval, the slew-rate control signal being input to the plurality of output buffers, whereinslew rates of the plurality of output buffers vary according to the input slew-rate control signal,the controller generates the slew-rate control signal that is activated after an end of the charge-sharing interval, andthe slew-rate control signal is not active during the charge-sharing interval.
