Abstract

Provided are a source driver for receiving a digital signal and providing a grayscale signal corresponding to the digital signal and a display device for displaying content. The source driver includes an amplifier configured to provide a grayscale signal, a second driving switch configured to provide the grayscale signal provided by the amplifier to an output node or block the grayscale signal, and a first driving unit including a first switch whose one end is connected to a first voltage and whose other end is connected to the output node and a second switch whose one end is connected to a second voltage and whose other end is connected to the output node, and configured to first drive the output node. The output node is first driven by the first driving unit and then second driven by the amplifier with the grayscale signal.
