Abstract: Provided are a source driver configured to drive a display panel and a display device including the same. A source driver configured to drive a source line of a display panel includes a digital circuit configured to receive and store digital pixel data, and an analog circuit configured to convert the stored digital pixel data into an analog-signal-type gradation voltage and output the analog-signal-type gradation voltage. A static current of the analog circuit is reduced in response to a value of a timing signal corresponding to a non-driving section of the display panel.
